Application On Research Of Deep Foundation Pit Supporting

The paper analyses the structure deformation of deep foundation pit basing on Control deformation of foundation pit, and dissertates the principle and design Method of control design of foundation pit's structure deformation. It predicts the foundation pit's deformation in finite element method .In the paper, the optimize design method of foundation pit is brought forward ,and the design method of foundation pit basing on deformation control is discussed. and level and vertical displacement is analyzed. The principle and major content of deformation control design are also discussed .The project choice for deep foundation pit is discussed in this paper. when the project is choose, the surrounding around foundation pit, excavated depth, geotec-hnology and hydrogeology condition, instruments and season are the most considered factors .The viewpoint of dynamic design on foundation pit and the analysis system of deformation prediction, and the data of measure, suggest that the displacement prediction of the foundation pit system is possible.The reverse analysis method was used in dissertating that the dynamic design in deep foundation pit project and construction with the help of information are becoming the development current of structure design and construction. Obverse and reverse analysis and design method can be used to optimize design, economize investments and ensure safety.
