摘要
Abstract
Taking a crisscross subway tunnel in Xi'an as the research object,a mathematical model of soil heat transfer under the joint influence of ground and tunnel heat flow is established to study the changes in soil temperature around the tunnel and the depth of soil constant temperature(the depth at which soil tem-perature is not affected by the tunnel).The soil tem-perature around the tunnel increases with the extension of subway operation time.The larger the passenger ca-pacity,the higher the soil temperature around the tun-nel.When the subway is in operation for 30 years,the soil temperature around the tunnel with a passenger ca-pacity of 2 000 people per train is about 4％higher than that of the tunnel with a passenger capacity of 0.The depth of soil constant temperature increases with the increase of passenger capacity.When the passenger capacities are 400,800,1 200,1 600 and 2 000 people per train,the depth of soil constant temperature is 65,65,66,67 and 68 meters,respectively.关键词
