摘　　要：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 monitoring earth pressure and displacement of diaphragm wall of deep foundation excavation of Yanji Street Station of Shanghai Metro line M8,the relationship between earth pressure in active area and displacement of diaphragm wall is studied in detail.The results show that the relationship between the earth pressure and the displacement of diaphragm wall may be expressed by hyperbolic model.The horizontal foundation coefficient of soil is increased with depth,and the trend slows at some point.
