摘　　要：针对西部寒区隧道的温度场问题,以有限差分为数值计算基础,以FLAC3D2.1软件为平台,以其内置的FISH语言为工具,编制了计算程序,该程序克服了FLA CD32.1软件本身不能考虑相变潜热等缺陷。最后用该程序对某工程实例进行了数值分析。The temperature field of tunnel in cold region is discussed method and FLAC^3D 2.1, a program is written in internal FISH language in this paper. Based on finite difference of FLAC^3D 2.1. The program overcomes the deficiency which is not taken into consideration latent heat of change at phases in FLAC^3D 2.1 . Finally, the program is applied to analyze the project in case. Results illustrate that the ProGraM is practical.
