Study On The Influence Of Deep Excavation On The Surrounding Environment

In recent years, with the accelerated process of urbanization, the urban land utilization is reduced, the utilization of underground space become the focus of the construction of today. More and more deep excavation is encountered in the process of urban construction.deep foundation pit engineering is often accompanied by complicated surrounding environment. The security problems of deep foundation pit engineering not only contains its own strength, deformation, etc. But also contains generated in the process of foundation pit excavation is sensitive to the surrounding environment. So the impact on the surrounding sensitive and complicated environment is paid more and more attention to the excavation of foundation pit.In this paper the jindu international square deep foundation pit engineering as the background, the impact on the surrounding environment of excavation of deep foundation pit are analyzed. The main contents are as follows:(1). This paper briefly introduces the foundation pit excavation is sensitive to the surrounding environment and the influence of the development.(2). This paper summarizes the overview of foundation pit excavation on the surrounding sensitive environment influence factors, forecast results, influence.(3). The influence of excavation on surrounding buildings are analyzed by using the finite element analysis software ABAQUS, analysis of excavation adjacent to the surface,the structure of the deformation in the process of situation, and compared with the measured data analysis, in the case of selecting reasonable parameters simulate the data have some reference value in engineering.(4). According to the simulated data and the analysis of the measured data of supporting pile parameter adjustment and checking calculation of strength and support strength.It is concluded that to improve the strength of the support can effectively reduce the settlement of surrounding buildings, and puts forward some suggestions for the construction of similar project.
