摘　　要：岩体结构的探测方法主要有直接观察法、物探法和钻孔观察法,由于岩体结构本身较为复杂,单靠某一种探测方法往往难以准确测定。采用探地雷达结合钻孔窥视的方法联合测定岩体的结构及破坏情况,发挥了探地雷达探测结果与钻孔窥视的优势互补作用,不仅解决了探地雷达探测深度浅的问题,而且克服了钻孔窥视观测岩体结构时空间断的缺点,能够为巷道围岩支护设计提供可靠的依据。Rock mass structure detection methods includes direct observation, physical exploration and drilling observation method. Due to complicated and affected by various factors, rock mass structure was often difficult to be accurately probed by one method alone. In this article, the probing of rock mass structure and failure adopted ground penetrating radar combining borehole observation to solve the problem of low probing depth of ground penetrating radar and space discontinuity in borehole observation, which plays the role of com- plementary advantages and a reliable basis for surrounding rock supporting design.
