Abstract

Considering the space effect，the general deformation mode of subway station foundation pit in sandy cobble stratum is acquired based on a large number of measured deformation data from 18 subway station foundation pits in Beijing. By establishing the relationship of the maximum deformation between any section at different distances(d) from the corner and the section in the middle，it shows that the general deformation rules can be expressed piecewise by Guassian Function based on the different ratio of length(L) to depth(H_e) and the type of pit support structure. And it can also determine the position of the maximum deformation section. On the basis of the general deformation mode，which is concluded by summarizing the above deformation rules，the foundation pit can be divided into the corner effect area and the plane strain area quantitatively. Based on this，the dynamic deformation control process can fully consider the space effect during the stage of design，construction and monitoring，and it can control the deformation economically and effectively.

Key words： soil mechanics sandy cobble stratum subway station foundation pit space effect general deformation mode dynamic control process
