过去探查已建工程的隐患,多是在分析观测资料的基础上采取开挖或钻探的办法。不仅工期长,投资多,且往往又给工程留下新的隐患。为此,近年来湖南省采用电法勘探堤坝隐患技术,先后对62处土石坝工程进行了探测,针对不同隐患采用不同探测方法进行了试验研究。实践证明,电法探测隐患准确、迅速,能为处理、加固工程设计及时提供可靠的依据。电法探测的基本原理是:工程有隐患时,会
In the past, the hidden dangers of exploring completed projects were mostly excavation or drilling based on the analysis of observed data. Not only long construction period, more investment, and often leave new hidden dangers to the project. Therefore, in recent years, Hunan Province has adopted the electric exploration technology for hidden dangers of levees and dams, and successively conducted 62 earth-rockfill dam projects, and conducted experiments and research on different hidden dangers using different exploration methods. Practice has proved that electrical detection of hidden dangers accurately and quickly, for processing, strengthening engineering design in a timely manner to provide a reliable basis. The basic principle of electrical detection is: When the project has potential problems, will
