由于土石坝结构的复杂性及其自身的特点,决定在探测技术上的困难很大。在现有的地球物理勘探方法当中,对于土石坝隐患的探测方法有很多,高密度电阻率法、探地雷达法等等都是较为成熟使用的隐患探测技术。鉴于在介绍土石坝自身特性后,采用瞬变电磁的方法通过对隐患模型进行实验研究分析,以便为在现场利用瞬变电磁法探测土石坝隐患奠定基础。
Due to the complexity of the earth-rock dam structure and its own characteristics, it is very difficult to determine the probing technology. Among the existing geophysical exploration methods, there are many detection methods for hidden dangers of earth-rock dam. High-density resistivity method, ground penetrating radar method and the like are all mature detection techniques. In the introduction of the characteristics of earth-rock dam itself, the use of transient electromagnetic method through the experimental study of the hidden model in order to make use of transient electromagnetic method to detect the hidden dangers of earth-rock dam in the field to lay the foundation.
