摘要
本文运用ABAQUS软件对武汉地铁2号线小龟山车站基坑开挖分别进行了二维和三维模拟计算。计算得到二维模拟条件下围护结构内力、变形和土体位移的变化趋势与三维相近,但相应数值均大于三维的情况,充分说明了基坑具有明显的空间效应。
This paper uses the ABAQUS software to make two-dimensional and three-dimensional simulation for Wuhan Metro Line 2 Xiaoguishan station foundation pit excavation. The calculation shows the retaining structure internal force, tr-ansformation and change trend of soil displacement on two-di-mensional simulation conditions is similar to 3D, but the corre-sponding values are greater than the three-dimensional, ful y demonstrates the foundation pit has obvious spatial effect.
