| 摘 要： | 根据防冻胀水泥杆与对应土层的实际的传热耦合，建立了其耦合传热的数值模型，结合冻结的初始条件和边界条件，采用有限差分法以及Simple算法，对数学模型进行了数值求解，结果表明土层冻胀临界的计算值与实际测试结果基本吻合。

| Abstract: | In this paper, basing on the problem that freezing extension of the soil soved by the heat pipe, illustrating the rationality and practicability of this method, according to the theory and process of the appearance of freezing extension soil. In combination with the initial conditions and boundary conditions, and by use of the finite-difference method and the SIMPLE programs, numerical results are gotten for the model. According to the numerical results of the model, some mechanisms of the freezing extension solved by the heat pipe are analyzed. |
