郑州市城郊铁路工程独柱高架车站抗震分析

结合郑州市第一座独柱高架地铁车站工程实例，采用三维有限元模型，对多遇地震下墩柱混凝土压应力、钢筋压应力、钢筋拉应力、墩柱稳定性应力进行分析，对罕遇地震下墩柱弯矩进行了分析。同时在抗震要求下，对结构强度，结构变形进行分析计算，结果表明独柱高架地铁车站主体结构在地震作用下是安全，可靠，能够达到抗震设计要求。

Seismic Analysis of Single Column Elevated Station In Zhengzhou Suburban Railway Engineerin

Combined with the first single column elevated station of Zhengzhou, analyzed the compressive stress of concrete,the tensile and compressive stresses of steel,stability stress in pier column under frequent earthquake using the finite element method. Further, moment of pier column under rare earthquake was analyzed. Based on the seismic requirements, the structural strength and deformation were calculated and analyzed, which showed that single column elevated station with large cantilever is safe and reliable, the structure meet requirements of seismic design .
