关于某工程施工阶段抗浮失效分析及加固方案

Analysis and reinforcement scheme of anti-floating failure in aproject during construction stage

通过对某工程地下室施工阶段抗浮失效构件损坏情况进行统计分析,确定抗浮失效的破坏特征.同时利用SAP2000有限元软件建立整体模型分析计算不同水压力时地下室构件的受力状态并分析其受损状况,分析结果表明施工阶段的抗浮能力不足导致地下室抗浮失效,并提出相对应的加固处理方案.

This paper determines the failure characteristics by means of the statistical analysis of the failure of the anti-floating failure component in the basement of a project. At the same time, an integral modeling analysis is conducted with finite element software of SAP2000 to analyze the stress state of the basement component and damage condition. Results show that the insufficient anti-floating ability of the basement in the construction stage causes these anti-floating failure,in the meanwhile, a corresponding reinforcement scheme is put forward.
