Stability Analysis Of High-Rise Residential Building Foundation Based On Huang-Huai College

The dense presence of the high-rise buildings makes it possible to engage in high-level building practice in the immediate vicinity of existing facilities such as buildings,transport facilities,rivers and lakes.As the adjacent river(lake)quiet living environment,a pleasant climate,the region more and more residential buildings loved by the public.However,considering the influence of the surrounding river environment of new high-rise buildings,the key problems of the near-river engineering practice are:the influence of river water level changes,earthquake and other sudden loads on the overall stability of the foundation pit structure.Based on this consideration,the stability of the basic engineering of the residential buildings near the Linhe River is studied based on the engineering background of the faculty building of Huanghuai College,which is based on the intersection of Kaiyuan Avenue and Wenming Road in Zhumadian City.The main contents are as follows:Based on literature review and field investigation,this paper summarizes and summarizes the structural features and supporting types of high-rise buildings.Combining the open-source avenue of Wenming Road and Zhuanmadian City,the residential building of Huanghuai College The mathematical fuzzy theory is introduced into the stability analysis of the foundation pit structure,and the hierarchical structure model which influences the stability of the supporting structure is constructed,and the stability of the structure is analyzed.The factors influencing the stability of the support structure are as follows:hydrogeological condition,supporting structure of foundation pit,seismic effect and close river influence.Combining with the in-situ geotechnical test and the in-situ test data,the physical and mechanical properties of silty clay are studied,and the soil nailing support scheme of foundation pit is put forward and its overall stability is evaluated.With ABAQUS finite element software,the stability of support structure during excavation was analyzed by numerical simulation.The results show that the lateral displacement of the excavation is small and the maximum lateral displacement is less than 2mm,and the supporting stress is much less than the designed strength.The stability of the retaining structure is high.Analyze the influence of the change of external load conditions on the supporting structure of "foundation" and "river water level change".With the help of ABAQUS finite element software,numerical simulation is carried out.First,the stability of foundation pit support structure caused by hydrological change in Linhe River is evaluated.Then,the overall stability of foundation pit support under sudden earthquake is analyzed.At the same time,the stability of the foundation pit in the process of changing the external load conditions of residential buildings is discussed.
