地铁围护结构地墙加长与土层扰动的关系

Relation between the lengthening of the underground wall and the disturbance of soil layer

针对扰动土对地墙围护结构工程中施工的不利影响,以某地铁车站地墙围护结构为例,利用同济启明星FRWS 7.2软件,分别计算出不同程度扰动土和不同长度的地墙围护结构下的整体稳定性、坑底抗隆起、墙底抗隆起等各个安全系数,为实际工程提供有利的依据。

In view of the adverse effects of disturbed soil on the construction of the wall surrounding structure project, taking the ground wall sur- rounding structure of a subway- station as an example, the software of Tongji Qimingxing FRWS 7.2 was used. The safety factors such as overall stability, anti-uplift of pit bottom, anti-uplift of wall bottom, etc. under undisturbed soil and wall enclosure structure of different lengths are calculated respectively, which provide favorable basis for the actual project.
