地下室抗浮设计若干问题探讨

Discussion about some problems on the anti-floating design of the basement

地下室抗浮设计首先应合理确定地下室抗浮水位标高,接着进行整体稳定性及局部稳定性的验算,当稳定性不满足要求时,需根据工程具体情况合理选择抗浮措施。施工期间按设计图纸要求分阶段控制地下室水位标高,对地下室上浮引起的结构变形进行分析判断。

In anti-floating design,the first and foremost thing is to reasonably confirm the anti-floating gauge height of the basement,and then check the global and local stability. If the stability does not fit the demand,it is necessary to make appropriate choice of anti-floating measures according to the specifics of the projects. Meanwhile,it is imperative to adopt a multi-phase control over the gauge height of the basement and make judgment on the deformation induced by the floating basement throughout the construction period.
