摘要
本文对路基土体内部的动力响应进行了分析,通过有限元方法研究了影响路基土体动力响应的影响因素。研究车辆荷载、路堤高度、基层模量及行车速度等影响因素处于不同工况时路基顶部的应力变化,并对这些影响因素进行了分析,在此基础上提出相应的建议,可为后续低路堤的研究提供参考。
In this paper,the dynamic response of the subgrade soil is analyzed,and the influence factors of the dynamic response of the subgrade are studied by the finite element method. When the influence factors such as vehicle load,embankment height,base modulus and driving speed are in different conditions,the stress change of subgrade top is studied.These factors were also analyzed,and the corresponding suggestions have been proposed,which would offer references for subsequent low embankment.
