摘要
裂隙岩体的温度场是岩体多场耦合中重要的研究内容之一,也是国内外研究的热点和难点问题之一。基于热传导方程的基础上,建立考虑岩体与裂隙水流热量交换作用的温度场数学模型,采用有限单元法进行了数值求解。研究结果表明:当岩块温度与水流温度存在温度差值时,二者之间会有一定的热量传递,并最终稳定于二者之间的某一温度。所建立的裂隙岩体温度场数学模型为裂隙岩体多场耦合分析奠定了一定的基础。
The temperature field of fractured rock mass is one of the important researches in the multi -field couplings .It is also one of the hot and difficult problems at home and abroad .Based on the heat conduction equation , considering the heat exchange of rock and fissure water , the paper built the mathe-matical model of temperature field and used finite element method to conduct numerical solution .The re-sult shows that when there is temperature difference between rock and water , there exists heat transmis-sion,and the temperature will keep a value between them .Finally, the model can settle certain founda-tion for multi-field couplings of fractured rock mass .
