摘　　要：微动探测可用于探测目标区域的地下空洞、活动断裂、覆盖层厚度、基岩面形态以及溶洞等。以江西九江高泉水库为例,详细介绍了现场微动勘探的测线布置、数据采集、数据处理分析、成果解释。实践表明:微动勘探技术是一种简便、快捷、对观测环境无特殊要求同时又不破坏环境的地球物理勘探方法,能够对病险水库大坝的隐患进行及时和有效的探测,并对堤坝隐患治理提供精确指导。Micro tremor exploration technique can be used to detect underground cavity, active fault, overburden thickness, bedrock surface shape, karst cave and so on in object region. Taking Ganquan Reservoir in Jiujiang City, Jiangxi Province for ex- ample, we introduced the field line layout, data collection, data processing and analysis and results interpretation of micro tremor exploration. The practice indicates that micro tremor exploration technique is a simple and quick geophysical prospecting method, which has no special requirements for observation environment and causes no damage to environment. The method can timely and effectively detect latent hazards of these defective reservoirs and dams and guide the treatment of these hazards.
