岩体渗流场与温度场的耦合问题是岩体水力学最重要的研究内容之一,随着越来越多的寒区工程问题暴露,对寒区岩体渗流场与温度场进行系统的分析势在必行.推导了考虑相变的温度场影响下的渗流场控制微分方程以及渗流场影响下的温度场控制微分方程,并利用FLAC3D3.0软件中的FISH语言编写程序模拟嘎隆拉隧道,在考虑相变的情况下,通过对比考虑渗流和不考虑渗流的温度场,得知不考虑渗流的影响会夸大冻融圈厚度的结果.

The coupling of seepage field and temperature field is one of the most important branches in rock mass hydraulics,with more and more engineering problems exposed in cold regions,and it is imperative to analysis the seepage field and temperature field of the rock mass in cold regions systematically. Firstly ,the differential equation of seepage control under the influence of temperature and the equation of temperature control under the influence of seepage are deduced,and a FISH language program is written to simulate Galong tunnel. Taking phase change into a consideration,the conclusion that the thickness of freeze-thaw circles will be exaggerated without considering the influence of seepage is drawn by contrasting the temperature fields in the seepage field or not .
