| 摘 要： | 通过分析重载铁路轨道结构的受力特征,得出车辆荷载在轨枕上的分担规律。基于二维弹性层状体系理论建立了重载铁路轨道结构的层状体系力学模型。利用MATLAB软件编制相应的程序计算出弹性层状体系的理论解,将得出的计算数据和大秦线实测数据做对比分析,检验出计算程序的正确性和弹性层状体系理论研究方法的可行性,为今后重载铁路轨道结构动力响应的研究提供了一套新的思路和方法。

| Abstract: | This paper obtains sharing rule of vehicle load on the sleeper by analyzing the force characteristics of the track structure. Based onthe two-dimensional elastic layered system theory, this paper establishes the mechanical model of the layered system under the rail structure.The MATLAB software program can calculate the theoretical solution of elastic layered system,and compared with the testing data on DaQin line, it can verify the feasibility of the validity of the calculation program and the feasibility of the elastic layered system theory method.This paper provides a new train of thought and method for the study of the dynamic response of heavy haul railway track structure in the future. |
