摘要:
随着高速铁路建设的快速发展以及既有线路的提速,列车的高速运行引起道砟结构颗粒的碎化、变形导致轨道的不平顺,造成工程病害,成为亟待解决的关键问题。本文对比分析了早期国内外道砟累积变形预测模型和模拟列车重复荷载的试验条件,提出已有预测模型已不适用于当下环境,并且指出还需进一步探讨试验方案的设计; 总结了道砟破碎的影响因素以及离散单元法在道砟累积变形和破碎研究中的应用,提出了进一步研究的建议。
Abstract:
As the rapid development of the construction of high-speed railway and the raised speed of existing railway line,the broken ballast particles and deformation of ballast structure resulted from high-speed operation of the train have caused engineering diseases,which became critical problems to be solved.Through comparative analysis of early prediction model of ballast accumulated deformation and the test conditions for simulating train repeated load,finding that the existing forecast model was no longer applicable to the current environment and the design of the test protocol needed to be further explored.The influence factors of broken ballast and the application of discrete element method in ballast accumulated deformation and broken research were summarized,some research recommendations were also suggested.
