堤坝隐患无损探测研究应用进展

Review of non-destructive detection for hidden defects of dams

对目前我国堤坝隐患探测技术的现状进行归纳综述,说明各种方法近年来的研究应用进展情况。主要介绍了常规电法、电磁法、地震勘探、示踪法和流场法的应用概况。由于各种方法技术都有其自身应用条件和局限性,任何单一的方法都不是万能的,有时在实践中若仅以一种参数作为解释的依据,可能难以取得预期的效果,因此,实践中一般采用综合物探方法来提高反演解释的精度。同时也简要介绍了综合物探方法在国内的应用情况,并提出研究发明新的堤坝隐患探测技术是必要的。

The achievements of detection technology for hidden defects of dams in China have been summarized in this paper. The author introduces different methods＂ application and research in recent years. The application of conventional electric method, electromagnetic method, seismic exploration, tracer method and flow field fitting method has been introduced. Each method has its application conditions and limitation. As no method is almighty, cross application of geophysical methods is recommended here to improve the inversion precision. The author has also introduced application status of integrated geophysical methods and pointed out that research of new methods is necessary.
