本文利用PLAXIS软件分别对不同高度柔性挡墙墙身宽度、墙身模量对水平位移的影响分别进行了详细的模拟分析,分析结果表明:墙背和墙面的位移都随着墙宽的增加而减小,但是墙背位移的减小幅度很大,因而位移相差很大,而墙面位移的减小幅度却很小,相差不大,挡墙宽度越小,墙面鼓出越明显;墙背水平位移曲线在墙身模量较小时呈波浪线形状,在墙身模量较大时,呈鼓形变位模式;墙面水平位移曲线则全部呈鼓形变位模式。
In this paper, PLAXIS software was used to simulate the effect of wall width and wall modulus on horizontal displacement of flexible retaining wall with different height. The analysis results show that the displacement of wall back and wall increases with the increase of wall width But the displacement of the back of the wall is greatly reduced, so the displacements vary greatly, but the reduction of the wall displacement is small, the difference is small, the smaller the width of the retaining wall, the more obvious the wall bulges; The horizontal displacement curve of the wall back showed a wavy line shape when the wall modulus was small, and the drum-shaped displacement pattern appeared when the wall body modulus was large. The horizontal displacement curve of the wall surface all showed a drum-shaped displacement pattern.
