【摘要】 研究目的:复杂的岩溶隧道易发生突水突泥安全质量事故,为了对隧道前方地质富水状况进行准确的探测,给隧道安全、快速施工提供超前地质依据。研究结果:通过结合水平超前钻探验证,证明在岩溶隧道依靠高密度直流电法对岩溶富水情况探测较为准确,为防止隧道发生突水突泥,保证安全、快速施工提供了有力保障。更多还原

【Abstract】 Research purposes:The accidents of water-bursting and mud-bursting can happen easily to the complex tunnel in karst area,so it is necessary to correctly predict the situation of geological rich-water in front of tunnel for the purpose of providing geological basis in advance for safe and rapid construction of tunnel. Research results:The level probing in advance shows the prediction of the karst rich-water with high-density direct current test method is accurate to karst tunnel,which can keep the tunnel from water-bursting and mud-bursting to safeguard the rapid construction of tunnel.更多还原
