【摘要】 隧道突水突泥会对工程建设带来巨大的安全隐患和经济损失,逐渐成为高风险岩溶隧道施工急需解决的关键科学技术难题。在系统收集整理大量岩溶隧道突水突泥实例的基础上,总结出包括地下水、岩组、地质结构面、岩层产状、沉积期古剥蚀面、地形地貌和降雨等7大主要地质影响因素,研究了岩溶水体和不良地质体在地球物理场上表现出的响应特征,即在地震波、电磁场的传播过程中,遇到该类介质时某种特殊的前兆信号信息,解译岩溶水体和不良地质体在地球物信息场上的响应特征,辨识导致灾变的前兆信息,并在实际隧道工程施工中得到了成功的应用,对建立突水突泥预测预报方法具有非常重要的理论价值和工程指导意义。更多还原

【Abstract】 Tunnel inrush of clay and water,which has become the key technology that needs to be solved for the construction of high risk karst tunnels,brings huge security risks and economic losses.On the basis of many examples of karst water inrush and sudden mud of tunnels,ground water,petrofabric,geological structure surface structures,attitude of rocks,deposition of ancient erosion surface,topography and geomorphology and rainfall were the main geological influence factors on water inrush and sudden mud.The response characteristics of karst water and unfavorable geological condition in the geophysical field have been researched.That is the particular type of precursor signal information when the seismic waves and electromagnetic waves encounter the karst water and unfavorable geological condition in its propagation process.The response characteristics of the karst aquifer and unfavorable geological body in the geophysical information field were interpreted.The precursor signal information that led to the disaster was recognized.This was successfully applied in the tunnel construction and was significant in the prediction of water inrush and sudden mud of tunnels.更多还原
