隧道裂隙岩体温度-渗流耦合数学模型研究

A study of mathematical model on coupling between temperature -seepage in fractured rock mass surrounding tunnel

随着越来越多特长深埋隧道工程的修建，围岩体所赋存复杂地质环境（ 渗流场、温度场与应力场等） 之间的相互影响作用已不容忽视。通过隧道裂隙围岩体渗透性能与热物理性能的等效连续化处理，初步建立了围岩体温度场与渗流场耦合作用数学模型，并应用于秦岭隧道工程。

With the construction of more and more deep buried tunnels with extremely large length, the mutual action among the complex geological environments in which the surrounding rock mass is situated can not be ignored anymore. In this article, through dealing with permeability and thermal physics of the rock mass surrounding tunnel by equivalent continuum method, a mathematical model on coupling of temperature field with seepage field in surrounding rock mass is established. At last, the model is checked by applying in the practice of Qinling tunnel project.
