大型地下室抗浮设计若干问题研究

Research on the anti floating design of large basement

在沿海地区或地下水位埋深较浅的地区,由于地下室抗浮水浮力设计不合理,造成地下结构开裂的事故时有发生。总结设计实践经验,对大型地下室的抗浮设计中涉及到的地下水位取值、抗浮措施选取、因抗浮措施失效造成地下室底板或外墙裂缝的原因分析及补强处理方法进行归纳。

This paper discusses several issues of the anti-floating design in large scale of basement which involve the determination of groundwater level,the measures selected in anti-floating design,the analysis of the cracks arise in the exterior wall or floor of basement due to failure in anti-floating design,and the reinforce techniques to resolve the failure.
