【摘要】 圆梁山隧道是正在建设中的渝怀铁路上的十大困难工程之首,施工中广泛采用红外辐射探测预测隧道掌子面前方含水情况,对加快施工进度、保障施工安全发挥了很大作用。这里从红外辐射机理入手,结合前期地质预报资料的统计分析对地质体红外辐射场分布规律及影响因素、掌子面红外探水判别标准等进行了研究。研究成果对圆梁山隧道的下一步施工以及类似的岩溶隧道施工具有重要的指导意义。更多还原

【Abstract】 YUAN LIANG SAN tunnel is the top one of the ten key projects in the construction of the railway from Chongqing to Huaihua. In its construction, the infrared ray method is regularly used for prediction of waterbearing bodies located at the front face of the tunnel and it plays a very important role for safety and speed of the tunnel construction. In the paper, we analyze the anomalous distribution of infrared ray field caused by temperature difference of waterbearing bodies and their discrimination conditions based npon the numerical modeling and the statistics of observed and predicted data. The results are significant to guide the constructions of the tunnel in the future and of those tuunels with the similar carst geology condition.更多还原
