摘要

针对土资源缺乏地区利用施工造成的碎石弃渣作填料的高速公路碎石渣路基，采用有限元软件PLAXIS动力分析模块，计算碎石渣路基在车辆动荷载作用下的动位移、加速度等动力响应特性，并与传统的填土路基进行对比分析，验证了碎石渣路基具有较高强度和较强变形恢复能力等优点[1-9]。

Abstract

The finite element analysis procedure PLAXIS was presented to predict the dynamic response of macadam subgrade under dynamic loading. The deformation and acceleration of the subgrade were calculated to obtain the dynamic characters. Compared with the traditional soil subgrade

the macadam subgrade has larger compressive strength and better deformation recoverability. The finite element analysis was performed to prove the feasibility to use crushed stones to construct subgrade on the area with little soil resource.
