Abstract
In order to improve the construction quality of foundation pit engineering,this paper takes the foundation pit engineering of a com-mercial building as an example,simulates the excavation process of foundation pit by using the finite element software ABAQUS,and conducts finite element analysis on the SMW construction method pile+front grouting steel pipe inclined brace combined support structure.By analyzing the changing trend of pile lateral displacement and surface settlement value during the excavation of foundation pit,To verify the applicability of SMW construction pile+front support grouting steel pipe diagonal brace combined support structure in soft soil foundation.At the same time,a single factor analysis is carried out on the SMW construction pile+front grouting steel pipe diagonal brace combined support structure,and the influence of soft soil layer thickness on the support effect is studied.The results show that the lateral displacement and surface settlement of pile will increase with the increase of soft soil layer thickness.Therefore,in the actual construction process,the thickness of soft soil layer is fully considered to ensure the safety and stability of foundation pit support.关键词
