Abstract

The high ground temperature is a prominent problem in the construction of deep buried long tunnels. Based on the analysis of high ground temperature in existing tunnels, the influence of high ground temperature on tunnel construction was divided into three situations, namely the harm to human body, effects on labor productivity and accident rate increasing. Then the high temperature heat sources during the tunnel construction were researched. The high ground temperature evolution law of famous tunnel in the history was studied by using comparative analysis method, also the reason of ground temperature anomalies and the heat transfer type of rock mass was obtained. Based on the geothermal gradient formula and the reliability theory, the risk probability model of high ground temperature was obtained in the deep buried long tunnel construction. The results show that the method can predict the high ground temperature in deep buried tunnel accurately.
