Research On Foundation Pit Stability And Anti-sliding Pile Reinforcement Effect Of Jiang'an Community's External Parking Lot

Retaining and protection for foundation pit with its profession and flexibility in construction and design,always is a debatable research problem.With the development of the secince and technology,especially a lot of analysis and calculation software for geotechnical(Li Zheng,Qin Star,Midas,etc).Retaining and protection for foundation pit needs consider mang things.In addition to the deep foundation pit supporting design,construction conditions and other factors,we must also take into account the impact of the foundation pit supporting system in the surrounding environment and the mutual influence of foundation pit.The complex geological conditions of large area deep foundation pit supporting methods research is a broad,program complex rock engineering research subject.Over a very large number of engineering practice and the research work,the domestic and overseas scholars has established the retaining and protection for foundation pit method about classification of relatively complete system.But in actual work,especially for Kunming external parking lot,deep retaining and protection for foundation pit,this kind of supporting problem still lack system support method classification.Based on Kunming external parking lot.All city deep foundation pit bracing for typical examples,through to the complex geological conditions,and follow the in-depth research excawations overall stability and local have additional load side wall stability to the principle of combining,evaluation under complex geological conditions,according to the foundation pit stability comprehensive classification methods selection supporting method and confirmed supporting schemes.I have achieved the following results in the engineering construction and design of the foundation pit:(1)studied in different support method of deep excavation stability influence.(2)retaining and protection for foundation pit methods for comprehensive classification.(3)stability analysis of foundation pit.(4)the retaining and protection for foundation pit schemes are selected.(5)checked site of engineering geology and hydrogeology conditions.(6)on the common waterproof curtain construction method made innovation.
