Influence of hydrogeological conditions of surrounding rock on heat deposition of underground railway tunnel
摘要：
结合工程地质及水文地质条件，通过深入分析地铁隧道外地层温度对距离（深度）和时间的梯度的解析解，揭示出岩土含水量对热扰动传播的影响。结合水文地质学达西定律，指出地下水流动对热沉积效应有显著影响。

Abstract：
Combined with engineering geological and hydrogeological conditions, reveals the influence of water content of the soil and rock on the thermal disturbance propagation by analysing the analytical solution of the gradient of the outer strata temperature of the underground railway tunnel to the distance (depth) and time. Based on the Darcys law of hydrogeology, points out that the groundwater flow has a significant effect on heat deposition.
