摘　　要：通过使用Abaqus软件对TRD工法墙施工展开研究,探究其周边土体位移变化情况。计算得出TRD工法墙施工期间土体深层水平位移的变化,包括土体的位移趋势,以及土体的位移变化。对比发现,TRD工法墙施工会导致土体深层水平位移的变化,当土体位移发生时,土体深层水平位移会随着TRD工法墙的位置变化而变化;经过有限元模拟与实际观察,3个沉降实测点的最大隆起值分别为7.1、7.02、5.65 mm,相对应的模拟值依次为3.06、1.74、1.64 mm,结果证明TRD工法墙的施工对周围土体影响较小。The construction of TRD wall is studied by using Abaqus software to explore the displacement change of surrounding soil.The change of deep horizontal displacement of soil during the construction of TRD wall is calculated,including the trend of soil displacement and the change of soil displacement.It is found that the TRD wall construction will lead to the change of the deep horizontal displacement of the soil.When the soil displacement occurs,the deep horizontal displacement of the soil will change with the position of the TRD wall.After finite element simulation and practical observation,the maximum uplift values of the three settlement measuring points are 7.1 mm,7.02 mm and 5.65 mm respectively,and the corresponding simulation values are 3.06 mm,1.74 mm and 1.64 mm respectively.The results show that the construction of TRD wall has little influence on the surrounding soil.
