摘要
在对Rankin土压力理论计算模式及其参数取值问题进行深入讨论的基础上,通过对基坑开挖过程中作用在围护结构的刚性挡墙、板桩墙及地下连续墙的实测土压力资料的分析,建议采用考虑土与结构相互作用的基于现场实测反分析的侧向土压力K值法计算模式。并通过一工程实例对K值作了探讨。
This thesis firstly studies the challenging issues on Rankin soil pressure model and its coefficient of c,φ,secondly analyses the cite measured active zone pressure worked on such braced structures as rigid retaining wall,pile plank and diaphragm wall.Based on the descussion above,one argument is given,that is,for the active zone soil pressure,the reasonable model is lateral soil pressure coefficient of K considering the interaction between soil and retaining structure.The value of K should be acquired from back calculation of cite measured data.
