摘要
运用有限元软件对路面结构进行数值模拟,分别对荷载、坡度作用及层间接触状态作用下的层底应力进行分析,总结设计方法中存在的不足。针对如何提高基层适用性,减少路面车辙,对路面结构设计指标、参数和结构组合做出优化,为确保基层在不同使用条件下的良好适用性提供技术支持。
By using the finite element soft,in this paper,the numerical simulation of pavement structure was conducted.The stress value of bottom layer was researched respectively under the load,gradient effects and interlayer contact and the shortcoming in the design method was summed up.According to how to improve the applicability of grass-roots level and reduce pavement rutting,the pavement structure design indicators,parameters and structure portfolio were optimized which could provide technical support to ensure good applicability of the grass-roots under different use conditions.
