Based On The FLAC3D Left Bank Of Daqin Excavation Stability Study

Along with our country’s urbanization advancement to vigorously push forward, the real estate industry vigorously investment development, all kinds of tall building arises at the historic moment, at a higher development of underground space development and at the same time is also popular. With the scale of the excavation of underground space, the stability of the foundation pit supporting is very important.This topic around the stability of foundation pit supporting this problem, from optimization of foundation pit supporting design scheme to application in FLAC3D numerical simulation analysis of the stability of foundation pit may produce the unstability of the internal and external analysis. This study in order to investigate the safety and stability of foundation pit as the main line, the combination of macro and micro analysis, field investigation and laboratory analysis, test and simulation method and synchronization, multidisciplinary knowledge cross comprehensive use, a variety of model to discuss the theory with practice analysis, a series of research methods to evaluate the safety of foundation pit stability.Hope that through this topic research, relevant to the safety and stability of the foundation research to provide a reference for analysis and reduce accidents and safety hidden trouble, increase economic efficiency, improve the national economy and promote the safety and stability of the foundation pit the pace of research.
