【摘要】 在结构抗浮设计中,常采用抗浮桩作为结构抗浮措施,然而在施工过程中,当场地地下水位突然升高造成浮力急剧增大时,往往造成抗浮桩的失效甚至结构的开裂破坏。对某一设有抗浮桩的大型地下车库的上浮事故,进行结构有限元分析,了解结构不均匀上浮的变形特征、结构损坏状况以及抗浮桩破坏情况,并进行了应急处理及加固方案分析,可供类似工程参考。更多还原

【Abstract】 Uplift piles are often used in structure anti-floatation design as anti-floatation measure.Which will result in the vitiation of piles and crack of structure due to enormous buoyancy force in the construction process.An entire finite element analysis of a floating underground garage with uplift piles is proposed,finding out the deformation characteristics of structure and damage of the piles and other structure elements.The emergency work and reinforcement program are supplied,which can be a reference of similar projects.更多还原
