摘要
基于我国的沥青路面设计理论及标准,选取典型半刚性基层路面结构及材料参数,采用BISAR3.0软件对不同荷载作用下的路面结构应力、应变和位移进行计算,并分析了各力学指标对道路结构的影响。结果显示:不同荷载模式对路面结构的影响相当大,这对进一步解释路面面层的一些破坏现象提供了有益的参考。
Based on the theory and standards of the asphalt pavement design, typical semi - rigid asphalt pavement structure and material parameters were chosen. To calculate the stress, strain, displacement of the pavement structure under different loads BISAR3.0 software was adopted and analyzed the impact of the mechanical indicator on the pavement structure. The results show that the impact of different load patterns on the pavement structure is quite large, which can provide a useful reference for further explaining the pavement damage phenomenon of the
