地下结构上浮及抗拔桩设计

The design of underground structure floating upward and anti-floating pile

分析了浮力对地下结构产生的危害,对设防水位确定的方法进行了阐述,根据相应规范,探讨了地下结构浮力计算的步骤,同时介绍了上浮处理方法及抗拔桩设计方法,提出了抗拔桩设计的注意事项,为抗浮处理提供了参考。

The disaster of buoyancy to underground structure was analyzed,and the method of fortification water level determination was explained.Based on corresponding codes,the calculation steps of underground structure buoyancy were discussed,the floating upward treatment and anti-floating pile design methods were introduced,and points for attention of anti-floating pile design were provided,so as to provide references for anti-floating treatment.
