地铁深基坑开挖对周围地表沉降的影响
Influence of subway deep foundation excavation on surrounding ground settlement
摘要
Abstract
In order to study the laws of building settlement on the surface and the upper surface during pit excavation,on the basis of theoretical analysis and combining with monitoring data from Shenyang Liutiao lake station excavation site,this paper proposed the surface subsidence numerical model,and analyzed the parameters for the calculation model.The results show that the numerical calculation model set up to consider supporting structure under lateral impact with a certain degree of rationality,can well predict the trend of surface subsidence around the pit;pit settlement calculation model established to achieve a quantitative analysis of the surface settlement can accurately calculate the settlement value at different distances around the pit surface.This study established the preliminary model for calculating the surface subsidence,which is of help in improving the design and construction process theory in analysis and prediction the ground subsidence of subway station in Shenyang region.关键词
