The Foundation Pit Supporting And Monitoring Research Of Hefei Aofu Time Square

With the rapid development of Chinese economic, the development of the construction industry is thriving.so the number of high-rise buildings and high-rise buildings are more and more, the depth is also more and more deep. The foundation pit engineering is a very complex project. It involves all aspects of the rock and soil mechanics and engineering. In the process of excavation, it is necessary to ensure the safety of the construction process and personnel and the surrounding buildings. Therefore in the analysis of foundation pit deformation law it needs to pass the construction information.and to feedback to the design and construction.Based on the theory of soil mechanics and foundation engineering, we study the foundation pit supporting scheme construction technology of Aofu time square. Using ANSYS software to simulate and analyze the actual excavation of foundation pit and the surrounding environment, including the horizontal displacement, the stress of the anchor cable.Combining with the actual foundation pit in this paper, the general scheme of foundation pit supporting project adopts natural slope and simple soil nailing support. The one or two stage of the pit is taken the natural slope at the junction, the pile anchor on the south. The upper part adopts the natural slope and simple soil nailing supporting. The field monitoring data shows that the variation of deformation of retaining pile and anchor stress is normal.
