Influence of hydrogeological conditions of surrounding rock on heat deposition of underground railway tunnel

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 Darcys law of hydrogeology, points out that the groundwater flow has a significant effect on heat deposition.
