摘　　要：绥芬河铁路采用单线套轨技术,以适应中、俄列车的通行需求。由于中、俄列车活载计算方法存在较大差异,通过对比两种规范列车活载换算出的均布荷载数值,提出CK活载等效加载图式,并针对绥芬河铁路曲线32 m简支T梁在曲线布置的二恒及CK活载作用下的空间受力复杂问题,建立梁格、实体有限元模型,深入分析总结结构纵、横向内力分布及应力情况,提出内外梁在恒载及CK活载作用下的横向分布系数,以便指导本工程设计,同时为同类工程提供技术支持和借鉴。The Suifenhe Railway adopts single track mix-gauge technology to meet the traffic needs of Chinese and Russian trains.Due to significant differences in the calculation methods for train live loads between China and Russia,this article proposes an equivalent loading diagram for CK live loads by comparing the uniformly distributed load values obtained from the conversion of live loads between the two standards.In response to the spatial stress complexity of the 32 m simply supported T-beam on the Suifenhe Railway curve under the two constant and CK live loads of the curve layout,this paper establishes beam grillage and solid finite element models to deeply analyze and summarize the stress and internal force distribution of the structure in the longitudinal and transverse directions.The lateral distribution coefficients of the inner and outer beams under constant and CK live loads are proposed,which guides the design of this project and provides technical support and reference for similar projects.
