| 摘 要： | 对某深大异步联合基坑工程进行计算分析,并从安全、经济及施工的角度对多个方案进行比选;对该工程交界面处实测结果进行了有针对性的分析,得到该区域深层水平位移及内支撑轴力在空间上的变化规律：深层水平位移接近零点与开挖深度之比约为1.6;深层水平位移累计量随交界面距离的增大而减小,影响范围约为开挖面高差的2倍;异步开挖对内支撑...

| Abstract: | A detailed introduction of great asynchronous combined excavation is given.The calculation and scheme comparison are made from the points of safety,economy and being easy for construction.The monitoring analysis on juncture is made with clear target,and the variations of deep horizontal displacement and supporting forces are obtained.The results show that the ratio of zero-point of deep horizontal displacement to excavation depth is close to 1.6,the accumulative value of deep horizontal displacement would d... |
