某地下室下沉原因及对结构安全性影响分析

Analysis on Causes of settlement of a basement and its influence on structural safety

某小区地下室局部出现不均匀下沉,该区域混凝土梁、板、柱、墙等构件出现不同程度裂缝损伤。结合现场对地下室变形、裂缝损伤的检查检测结果,采用数值模拟方法对地下室进行内力分析,分析判断地下室下沉及裂缝产生原因,并就地下室下沉对该地下室结构的安全性影响进行分析。

Uneven settlement occurred in the residential area of a basement,some crack damage has been discovered in concrete beams,plans,columns and walls. According to the inspection results of damage and deformation of the basement,the internal force analysis of the basement was carried out by means of finite element method,causes of settlement of the basement and its influence on structural safety were analyzed.
