摘要： 运用有限元分析软件ABAQUS，对考虑空间几何尺寸影响的深基坑模型试验进行数值模拟。分析得出深基坑模型的最佳比例尺寸是：主动区土体长度与悬臂板的长度之比为1.5，被动区土体长度与悬臂板的入土深度之比为3.0。

Abstract: The influence of the space dimensions on the deep excavation is investigated throughout the model tests as well as the numerical simulations by using ABAQUS software. The results indicate that the optimized deep excavation dimensions in a model are: the ratio of length in the active zone B1 over the cantilever length is 1.50. The ratio of length in the passive zone B2 over the embedment depth of the cantilever portionL2 is 3.0.
