某超大圆形基坑三维有限元分析

摘要

Taking the extra large round foundation engineering as an example,the paper establishes actual three-dimensional finite element calculation model and parameter selection,and explores three-dimensional numerical simulation of various round foundation excavation mode.Combining with local hydrogeological condition,it points out controlling and design according to foundation deformation,which has guiding meaning for similar engineering construction.%以某超大圆形基坑为工程实例,建立工程实际的三维有限元计算模型和参数选取,探讨了圆形基坑在各种开挖模式的三维数值模拟,并结合当地水文地质条件指出应按基坑变形控制设计,对同类工程施工具有指导意义。
