工学路面性能指标释
pavement modulus back-calculation路面模量反演
已知一个路面结构的组成（如路面各层的厚度和材料类型等）和力学参数（如路面荷载、路面各层泊松比和模量等），可准确地计算出路面弯沉值或弯沉盆。因该弯沉盆与路面结构组成和力学参数之间存在唯一的一一对应关系，故根据实测的路面弯沉盆即可反算出路面结构的组成和力学参数，此为路面结构反演分析。但由于路面弯沉与路面结构组成、各层力学参数之间的关系式不是一个可简单计算的显式，且实测的弯沉盆数值难免有误差，很难与理论结果精确相等，故上述反演分析过程十分复杂。为减少反算的参数数量和提高反算的精度，根据路面评价的需求，一般仅反算路面各结构层的模量这一力学参数，即路面模量反演。
