摘　　要：以某地下变电站工程混凝土墙体为工程基础,进行了墙体内存在暗柱时的收缩应力分析,并与墙体内无暗柱的情况进行对比。得出如下结论:施工阶段,墙体有、无暗柱时的墙体收缩应力分析结果相差不大;当墙体内存在暗柱时,施工期收缩裂缝主要分布于墙体与暗柱的交界处。Based on the concrete wall of an underground substation project,this paper analyzes the shrinkage stress when there are hidden columns in the wall,and compares it with the case without hidden columns in the wall.The conclusions are as follows:in the construction stage,there is little difference in the analysis results of wall shrinkage stress with and without concealed columns;when there are concealed columns in the wall,the shrinkage cracks during wall construction are mainly distributed at the junction of the wall and concealed columns.
