| 摘 要： | 以天津某交通枢纽工程为例,通过基坑开挖过程中水平支撑结构板内力、围护结构及墙后土体水平位移实测资料分析,得出了逆作法异于顺作法的变化规律,由分析结果可知逆作法位移小的特点,为类似工程提供参考。

| Abstract: | It takes the traffic terminal of Tianjin for example,through analysis of the actual measurement data on the slab stress of the structural lateral bracing and the horizontal displacement of the space enclosing structure and the soil body behind the wall during the excavation,the different changing discipline between up-down construction and normal construction is concluded.It is shown that the up-down construction can cause little displacement and stress.It also provide reference for the up-down construction... |
