Gantry Pile - Anchor Structure In Foundation Pit Engineering And Research,

With the exending of city construction,the decneasing between the space of the building,and the deeping of the fundation pits,the effect of foundation pits project on the envonment is incneasing clear.On the other hand,new building situation arouses new challenge for the foundation pits project,on the other side,it also provide a lot of chances.This paper link the concrete of foundation pits project,takes the enviornment of the foundation pits for the controled aim,base on summarizing the experience,putsforward the new form of door tram_spwclly supporting,builds on the model ofconcise mechamics,puts forward the counter model of controled target and deforming in the foundation pits,adopts mang kinds of the method about supervising.It puts forward the counted model of elasticity foundation.In the model of concise mechanics,uses langjing soil's theory to count edge. The method is simple and clear.This paper is in progness on the discussion of the foundation pits subsiding,horizontal moving and getts the data from digging to the end of project of foundtion pit.The paper adopts mang method to analyze the deforming of foundation pits,drawst the chart of swbsiding's and horizontal moving's ratio,and then,gets the conclusion of eternal ratio.The project was very good after it was put into practice.The deforming of its enuironment was satisfied with the designed demand,the horizontal moving to themodel of deformed count is less 20%.It indicates that the door fram_spudlysupporting being contormed to the realistic condition.The door fram_spudly supporting is project value to control the deforming.
