换乘地铁车站抗浮设计

通过对各种抗浮措施的对比分析，确定了地下车站的抗浮适宜采用大直径人工挖孔抗拔桩。对于结构不同部位的刚度和受荷都不均匀的复杂换乘车站，采用空间有限元模型计算可以达到理想的结果。通过对一在建的大型地铁换乘车站的计算和分析讨论，提出了抗拔桩平面布置应遵守的原则，进而论述了车站抗浮计算及抗拔桩设计的全过程，可为今后复杂大型地下空间结构的抗浮设计提供参考。

Anti-floating Design for Metro Transfer Station

Having contrasted all anti-floating measures,I find out that it's better to apply big manually-bored uplift pile to conduct anti-floating for the underground station. For the complicated transfer station with structure bearing different stiffness and different loads,it's better to apply three-dimensional FEM (finite element method) model calculation so as to get satisfying result. After analyzing and calculating the large metro transfer station under construction,this article proposes the principles for the...
