［摘要］以天津某交通樞紐工程為例，通過(guò)基坑開(kāi)挖過(guò)程中水平支撐結(jié)構(gòu)板內(nèi)力、圍護(hù)結(jié)構(gòu)及墻后土體水平位移實(shí)測(cè)資料分析，得出了逆作法異于順作法的變化規(guī)律，由分析結(jié)果可知逆作法位移小的特點(diǎn)，為類似工程提供參考。

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 considering some kinds of factors.

Keywords:deep excavation; up-down construction; monitoring analysis
