浅覆土大盾构对临近建筑物影响的有限元分析

FINITE ELEMENT ANALYSIS ON EFFECT OF BIG SHIELD CONSTRUCTION UNDER SHALLOW SOIL AROUND THE BUILDINGS

摘要: 采用浅覆土大盾构施工难免对临近已建建筑物造成不同程度的影响。本文使用有限元数值分析,计算外滩通道工程中,浅覆土大盾构施工产生的竖直沉降和水平位移,从而分析对临近已建建筑物的影响。

Abstract: Big shield Construction under shallow soil will inevitably effect the buildings around. Finite element analysis will be used in this article, calculate the vertical and horizontal displacement, to simulate the effect in the project of Waitan Tunnel, Shanghai.
