The temperature field of deep tunnels and the development of deep mineral resources involve the thermal conductivity of rock mass. For the nonlinear change rule of effective thermal conductivity of fractured rock mass under normal stress, based on the two-part Hooke's model and effective thermal conductivity series-parallel theory, a theoretical model of effective thermal conductivity of fractured rock mass under normal stress was established, and the influences of model parameters on the effective thermal conductivity of fractured rock mass under stress were analyzed. Through the numerical simulation results of the change of temperature field in Nigel Tunnel, the reliability in engineering application of the model was verified. The results show that, the theoretical model prediction results are in good agreement with the test data. The effective thermal conductivity of the fractured rock mass in the low stress stage is mainly affected by the soft part of the pore-slit closure, and increases nonlinearly with the increase of the stress. While the effective thermal conductivity of the fractured rock mass in the high stress stage is mainly affected by the hard part of the pore-slit closure, and increases slowly in an approximately linear manner with the increase of the stress. The larger the angle between the fracture surface and the direction of heat transfer, the smaller the effective thermal conductivity of the rock at the same stress, and the higher the degree of non-linearity with the stress change. Comparing the numerical simulation results with the measured data, the thermal conductivity of the intact rock mass is on the large side, the effective thermal conductivity obtained by the stress-independent effective thermal conductivity model is on the small side, and the coupling model of normal stress and thermal conductivity is more in line with the actual measured values.

深部隧道温度场及深部矿产资源开发均涉及岩体导热性能问题。针对法向应力下的裂隙岩体有效导热系数非线性变化规律，基于双弹簧Hooke模型与有效导热系数串并联理论，建立了法向应力作用下裂隙岩体有效导热系数理论模型，分析了模型参数对应力作用下的裂隙岩体有效导热系数的影响，并通过尼格隧道温度场变化的数值模拟结果，验证了该模型工程应用的可靠性。结果表明：理论模型预测结果与试验数据吻合较好；低应力条件下，裂隙岩体有效导热系数主要受软体孔裂隙闭合影响，有效导热系数随应力增大呈非线性增大；高应力条件下，裂隙岩体有效导热系数主要受硬体孔裂隙闭合影响，有效导热系数随应力增加呈近似线性缓慢增大；裂隙面与热传递方向夹角越大，相同应力条件下的岩体有效导热系数越小，随应力变化的非线性程度越高。数值模拟结果与实测数据的对比表明，完整岩体导热系数偏大，与应力无关的有效导热系数模型得到的有效导热系数值偏小，而法向应力与导热系数耦合模型得到的结果更符合实际测量值。
