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.
本文運用ABAQUS 軟件對武漢地鐵2號線小龜山車站基坑開挖分彆進行瞭二維和三維模擬計算.計算得到二維模擬條件下圍護結構內力、變形和土體位移的變化趨勢與三維相近,但相應數值均大于三維的情況,充分說明瞭基坑具有明顯的空間效應.

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.
