摘要
圆形基坑围护结构的工作性状不同于条形基坑,其围护结构与土体共同作用的空间效应及时变性非常明显.本文对某特深圆形基坑进行了施工全过程的三维弹塑性分析和模拟,并详细说明了考虑空间效应及时变性分析的具体实现方法,结果表明,对于这类复杂的基坑工程,进行考虑结构与土体共同作用的施工全过程三维数值分析和模拟是完全有必要的.
Working status of the circle pit is different that of,from the rectangle pit,because the time effect and spatial effect of the interaction between the excavation support and the soil are distinct. In order to reveal the time effect and interaction, 3-dimensional non-linear numerical analysis is carried out in which the excavation is considered. The analysis results show that investigation of the interaction between soil and structure and the simulation of excavation process are necessary in such circle deep pit.
