摘　　要：阐述了我国堤坝隐患探测技术的应用情况,总结了堤坝隐患探测技术在我国实际应用中探测结果不确定性的主要原因,分析了介质材料的多样性和介质特性的不确定性对探测结果的影响、被探测对象中隐患尺度和仪器分辨率的矛盾、探测结果解读的不确定性和困难性等问题.建议加强堤坝介质特性对探测结果的影响以及现场比对试验研究,多种隐患探测技术的综合应用研究,加强理论和仪器应用技术的研究和跨学科技术人员的培训.The application situation of detective techniques for hidden troubles of dams and dikes in China is systematically expounded. Three key problems about uncertainty of detective results in practical applications are summarized and analyzed; the first is the variety of medium materials and uncertainty of its characteristics which will impact the detective results seriously; the second is the contradictions between the scale of hidden troubles in detective objectives and apparatus resolution powers; the third is the uncertainty and difficulties in interpretation of detective results. Finally, some countermeasures and recommendations are presented so as to strengthen experimental studies on the detective impact caused by different mediums, to apply various detective techniques to the same project in order to compare the results, and to train technicians with multi-subject knowledge in order to enhance their comprehensive diathesis.
