【摘要】：地熱是拉日鐵路吉沃希嘎隧道施工中的主要工程地質(zhì)問題,查明隧址區(qū)地熱分布特征,并且制定高溫熱害防治措施非常重要�？辈熘薪Y(jié)合物探異常數(shù)據(jù),布置鉆孔實測地溫,繪制測溫曲線,揭示了隧址區(qū)地熱分布規(guī)律;通過鉆孔測溫數(shù)據(jù)和地溫梯度值對隧道地熱異常區(qū)地溫分級和預(yù)測。同時在分析區(qū)域地熱地質(zhì)背景的基礎(chǔ)上,較為詳細地評價了地熱成因及高溫熱害對隧道建設(shè)的影響,并給出了相應(yīng)的防治措施。
[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.
