钻孔灌注桩对冻土温度场扰动数值模拟

首先提出了研究冻土区钻孔灌注桩周土体温度状况及回冻过程具有重要实践意义，然后对描述其物理现象的控制方程进行简单说明，最后运用有限元软件对其进行数值模拟，并与昆仑山试验场数据进行对比验证，以期该方法能够用于桩周土体温度状况及回冻过程预测。

Numerical Simulation of Perturbation of Frozen Soil Temperature Field by Bored Piles

It firstly proposes that it is of great practical significance to study the soil temperature conditions around bored piles and the refreezing process in frozen soil areas and then briefly describes the control equations describing its physical phenomena. Finally, the finite element software is used to conduct numerical simulation and compare and verify with the data from the Kunlun Mountain test site. It is hoped that this method can be used to predict the soil temperature around the bored piles and the refreezing process.
