【摘要】 岩溶隧道灾害预报是隧道快速安全施工的重要技术保障,以沪蓉西高速公路齐岳山隧道为工程背景,通过地质调查和分析,利用TSP地震波探测方法,地质雷达探测和超前水平钻探对YK326+790~YK329+810岩溶发育和岩性变化段进行了预报,基本探明了掌子面前方岩溶发育情况和岩性变化带,为及时制定处理预案提供了科学的依据。更多还原

【Abstract】 Geological disaster forecast of karst tunnels is an important technical support to safe and fast tunnel constructions.Based on the engineering background of Qiyue Mountain Tunnel in the west section of Hu-Rong Highway,through geological survey and analysis,and using Tunnel Seismic Prediction method,ground penetrating radar,an advanced drilling geological prediction detection was done on the area of YK326+790～YK329+810,and in front of the tunnel face,karst development area and lithology changes belt have been essentially detected.A scientific basis of timely treatment plans are provided.更多还原
