[Abstract]:Geothermal is the main engineering geological problem in the construction of Jivoxiga Tunnel in La-Japan Railway. It is very important to find out the characteristics of geothermal distribution in the tunnel area and to formulate the prevention and control measures of high temperature heat damage. Combined with the geophysical anomaly data, the paper arranges the measured ground temperature of the borehole, draws the temperature measurement curve, and reveals the geothermal distribution law of the tunnel site, and classifies and predicts the geothermal temperature of the anomalous area of the tunnel through the borehole temperature measurement data and the geothermal gradient value. On the basis of analyzing the geological background of regional geothermal, the paper evaluates the causes of geothermal and the influence of high temperature heat damage on tunnel construction in detail, and puts forward the corresponding prevention measures.
