摘　　要：分析了独柱式长悬臂高架车站在抗震概念设计方面存在的不足,指出了当前设计方法存在的问题。通过对重庆地区两个高架车站的计算,证明此类结构的墩柱不考虑抗震设计的做法欠妥。鉴于墩柱在车站结构中的重要地位和它接近静定结构的受力状态,建议适度提高其抗震设计标准。The shortcomings of single-column and long cantilever elevated station in the seismic concept design were analyzed,and the problems about current design method were presented.The calculation results of two elevated stations in Chongqing show that the method without considering seismic design for pier column has defect.Because of the significant position of the pier column and its load behaviors of statically determinate structure,the requirements for its seismic design should be improved reasonably.
