摘　　要：为保证岩溶区隧道施工安全,采用综合地质预报方法对隧道前方不良地质体进行探测。以某岩溶隧道为工程背景,通过地质分析研究了隧址区的岩溶发育特征,利用TGP和地质雷达法对K65+337处的溶洞进行了准确的预报,详细探明了溶洞规模、位置以及含水情况,探测结果与实际揭露相吻合。针对揭露的溶洞特点,提出了采用填堵法和引排水法相结合进行综合治理,通过对治理后围岩的变形监测,验证了治理方案的有效性,为类似溶洞处治提供了参考和借鉴。In order to ensure the safety of the tunnel construction in the karst area,the comprehensive geological forecast method is adopted to detect the bad geological body in front of the tunnel.Taking a karst tunnel as the engineering background,the karst development characteristics of the tunnel site area were studied through geological analysis,and the karst cave in K65+337 was accurately predicted by TGP and geological radar method.The scale,location and water content of the karst cave were proved in detail,and the detection results were consistent with the actual disclosure.According to the characteristics of the exposed karst caves,the combination of filling method and drainage method is put forward.By monitoring the deformation of the surrounding rock after treatment,the effectiveness of the treatment scheme is verified,which provides reference and reference for the treatment of similar karst caves.
