摘 要: 在冻土路基温度场模拟和稳定性分析中,冻土路基热物性参数的取值是至关重要的。基于优化的遗传算法,本文提出求解冻土路基热物性参数的反演方法,利用该方法对青藏公路冻土路基进行热物性参数反演,将计算结果和实测数据相比较,结果表明,在仅给定各反演参数取值范围的条件下,对常规遗传算法优化后进行冻土热物性参数反演具有一定的可行性和实际的工程意义。 It's important to decide thermal parameters in simulating temperature field and analyzing stability of frozen soil roadbed.Inverse analysis which based on improved genetic algorithm for thermal parameter of frozen soil is proposed and applied in deciding frozen soil thermal parameters of Qinghai-Tibet highway in this paper.The little difference between computed result and the observed has proved that it is feasible to inversely calculate thermal parameter of frozen soil by improved genetic algorithm,given only the parameters scope.
