摘　　要：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。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 com- plicated transfer station with structure bearing different stiffness and different loads, itt 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 plan layout of uplift piles and then relates the whole process of the station anti -floating calculation and uplift design which can provide the reference to design anti - floating for the compli- cated, large scale underground structure.
