在对上海地铁M8线延吉中路站基坑主动区土压力和地下连续墙水平位移实测资料分析处理的基础上,就主动区土压力强度和连续墙水平位移之间关系进行深入研究。分析结果表明,土压力和位移之间关系与双曲线具有很好的相关性,土体水平基床系数沿深度增加,但超过一定深度后增加趋缓。
Based on the analysis of the measured data of the earth pressure and the horizontal displacement of the diaphragm wall of the foundation pit in the Yanji Zhongji Station on the M8 line of Shanghai Metro, the relationship between the earth pressure intensity in the active area and the horizontal displacement of the diaphragm wall is studied in depth. The analysis results show that the relationship between soil pressure and displacement has a good correlation with the hyperbola, and the coefficient of soil bed horizontal bed increases along the depth, but increases slowly when the soil depth exceeds a certain depth.
