摘要
由于边界条件和初始条件的复杂性,路堤能量的偏微分方程的精确解很难求得,本文通过对路堤的温度采用差分计算以求其数值解法的方法,从理论上获得路堤任意时刻温度情况,为寻求防止寒区道路路面破坏措施提供理论上的依据。
Because of the complexity of boundary and initial condition, the exact result of the energy equation cannot be worked out. In this paper,by applying the method of number calculating to obtain the approximate result, the temperatures of the roadbed in every instant can be known to seek the approach of avoiding road crust' s damage.
