With the continuous development of urbanization, the scale of the city is expanding, which leads to the problem of urban land shortage. In the planning and construction of some cities, because plain land is very scarce, most buildings are built on low hillsides. The concrete analysis of plain building construction and hillside building construction shows that the bearing capacity and load of hillside building construction are obviously different from those of plain area, so in the building construction of the same structure, the design requirements of hillside area construction are better and the specific operation is more difficult. In order to improve the hillside construction environment, the effect of foundation treatment must be strengthened, and the concrete building construction also needs comprehensive and detailed structural design and analysis. In a word, the construction of multi-storey buildings on slopes, whether structural design or foundation treatment, must be professional and scientific, so it is of great practical significance to analyze the specific content of this aspect.
1 foundation treatment of multi-storey building on inclined hillside
Basic analysis of 1. 1
In the foundation treatment of multi-storey building construction on sloping land, the first work to be done is foundation analysis. Basic analysis includes two aspects: ① Geological analysis. For the construction practice of multi-storey buildings, the stability of geological structure ensures the stability of the structure, so it is necessary to analyze the geological movement of a specific area with soil structure, so as to better judge the engineering properties of the regional soil structure. ② Environmental analysis. Regional precipitation and some frequent disasters (geological disasters, meteorological disasters) will affect the stability of buildings, so in the basic analysis, it is necessary to master the environmental elements, so as to achieve advantages and avoid disadvantages in the specific design.
1.2 foundation design and treatment
In the case of basic analysis, it is an important principle to use the data and information obtained from the analysis to design and treat the foundation treatment of inclined slope. As far as design treatment is concerned, if there is obvious geological movement in this area, it is necessary to emphasize the seismic capacity of buildings in the design. If the soil moisture in this area is relatively high, it is necessary to improve the moisture-proof registration of building structures in specific structural design. In short, the basic design and processing need to be carried out on the basis of specific data analysis, so that the rationality of the design will be more obvious.
2. Specific contents of structural design of multi-storey buildings on slopes
From the current structural design analysis of multi-storey buildings on slopes, there are rich contents. Only by strengthening these contents and designs can the overall design be improved [2].
2. 1 foundation load
In the structural design of multi-storey buildings on slopes, foundation load is an important design content. As far as the concrete analysis of foundation load is concerned, two requirements should be met: ① to ensure the horizontal balance of load. The uneven horizontal load of the foundation on the inclined hillside will lead to the bearing of the building structure tilting to a certain surface or point, which is easy to cause the structure to collapse. Therefore, it is necessary to deal with the load of the horizontal foundation in the specific design to achieve the purpose of horizontal balance. (2) The load should be strengthened in the vertical direction. Because the foundation load is the largest in the multi-storey building structure, it is necessary to strengthen its vertical stress to avoid cracks caused by the increase of geological load.
2.2 Bearing capacity of each structural layer
In the structural design of multi-storey buildings on sloping land, the load-bearing design of each structural layer is also an important content. From the concrete analysis, the stress layer of multi-storey building is mainly divided into three parts: ① the upper part is stressed. The bearing capacity of the upper stress layer is the smallest, so only the specific bearing capacity needs to be calculated and considered in the specific design. ② The middle structure is stressed. The intermediate structure not only supports the upper part, but also exerts pressure on the lower structure. Therefore, when designing the intermediate structure, materials with higher structural stiffness and strength but stronger texture should be selected. ③ substructure. The substructure supports the whole building, and its bearing capacity is the most obvious, so the structural density should be adjusted appropriately in the specific design. In a word, the rationality of the design will be more prominent by analyzing and designing the load-bearing of each structural layer.
3 Measures to improve the structural design and foundation treatment effect of multi-storey buildings with inclined mountain skin
In order to improve the structural design and foundation treatment effect of multi-storey buildings on slopes, it is necessary to summarize and analyze data from concrete construction practice to make all aspects more perfect. The following measures are summarized according to the data to improve the specific effect [4].
3. 1 Grasp the influencing factors of stability from multiple angles.
From the specific analysis, grasping the influencing factors of stability from multiple angles and applying them to the specific design and treatment will obviously improve the overall design and treatment effect of the building. From the specific analysis, the so-called multi-angle mainly refers to three aspects:
① Geological stability angle. There are obvious stress differences in the geological structure of inclined hillside, and the original structure is easy to be destroyed when disturbed by the outside world. Based on this situation, it is necessary to analyze the unbalanced phenomenon of inclined hillside structure in the process of foundation treatment, so as to change the original structure through engineering measures and ensure its stress balance.
② Environmental stability. Considering the specific design, architectural design needs to be able to resist unfavorable factors in the environment, such as strong winds and earthquakes. Therefore, in the specific design, it is necessary to investigate and analyze the regional environment, and carry out targeted design according to the environment.
③ Load-bearing stability. The obvious feature of multi-storey buildings is that the bearing capacity of the lower part is higher than that of the upper part. Therefore, in the design, the bearing density and required material properties of the lower part are better than those of the upper part, so that the multi-layer structure will not be top-heavy. Comprehensive analysis shows that the safety of multi-storey buildings will be improved obviously if the stability analysis and design of the above three aspects are done well.
3.2 Strengthen design analysis and calculation
Strengthening the analysis and calculation of design is also the main strategy to improve the design and foundation treatment effect of multi-storey buildings on slopes. As far as foundation treatment is concerned, the analysis and calculation of the design is mainly due to the spatial instability of the soil structure on the slope, so it is necessary to emphasize the stability of the structure in the specific design. From a practical point of view, most of the slope foundation treatment uses column load for foundation reinforcement, but the density of column load will affect the concrete stress structure, so it is necessary to determine the density and distribution range of column load through accurate calculation to improve the effect of foundation treatment.
In addition, in the structural design of multi-storey buildings, the bearing capacity and corner stress of foundation, substructure and superstructure are all important factors to be considered, so in specific design, the bearing capacity and load of each part can be more accurately grasped by strengthening analysis and calculation. With accurate data calculation, the design error will be significantly reduced and the quality of architectural design will be improved in an all-round way.
3.3 Emphasize the professionalism of personnel
In the design of concrete multi-storey structure and the reinforcement of foundation treatment effect, the third important measure is to improve the professional quality of personnel. From the practical analysis, whether it is the design of foundation treatment or multi-storey structure, professional design concepts and methods are needed. If there is a problem with the professional quality of the personnel in the design, the design error is inevitable. Therefore, in the specific design, on the one hand, we should strengthen the specific professional ability of designers, on the other hand, we should do a good job of expert appraisal of personnel design schemes. The former aims to improve the basic quality of scheme design, while the latter aims to optimize the scheme. Therefore, no matter from the perspective of design quality or design optimization, the professionalism of personnel must be valued.
The structural design and foundation treatment of multi-storey buildings on slopes have an important influence on the stability of the buildings themselves. Therefore, analyzing and discussing the specific contents of foundation design and building structure design can provide reference and guidance for design practice and improve the effectiveness of design work.
The structural design and foundation treatment measures of the above-mentioned multi-storey buildings were collected and arranged by Zhong Da Consulting Company.
