Foundation Pit Deformation Monitoring Numerical Simulation Analysis Of The Xin Ya International Hotel In Fuxin

With the increasing urban building height, the excavation depth of the base also increases, thus give rise to a large number of excavation engineering. As to excavation engineering complexity, computational theory of the foundation pit deformation is still not mature enough, so Pit Deformation Analysis have great practical significance. In this paper, Fuxin Xin Ya International Hotel excavation engineering as the background, combination of the theoretical analysis, field monitoring and numerical simulation and other means, conducted in-depth research on the deformation of the foundation pit supporting structure, including the following aspects:(1) Summarized the basic types of excavation support system, summed up on the supporting structure of excavation engineering design theory and the foundation pit deformation calculation method at home and abroad, described the scope and the economy of the support structure, described in detail of the pile-anchor retaining structure calculation theory;(2) Combined with Fuxin Xin Ya International Hotel excavation engineering, collation and analysis the data obtained in the on-site monitoring process, obtained the horizontal and vertical displacement of the supporting piles、the crown beam horizontal displacement and the variation of the vertical displacement of the surrounding buildings on the deep excavation process;(3) Introduced the basic idea of the finite element method, using finite element software ADINA simulated the foundation pit excavation,got the deformation and internal force of the supporting piles under working conditions. Analyzed the measured data and the simulated data, and makes the specific analysis between the differences. Knew the key parts of the Pit Supporting Structure, and provide a reference for the design of the supporting structure.
