Abstract:: Conventional dam saturation line inspection methods are limited by the limitations of spatial andtemporal distribution , damage to the instruments, and instruments are not installed, so the application is re.stricted. In view of the fact that soil moisture content is proportional to its electrical resistivity, this article triedto apply high-density resistivity method to detect dam saturation line, this method has no need to drill, and ithas flexibility, a small amount of engineering and high resolution. The actual works based on high-density re-sistivity method for dam saturation line test, and compare with the method of Osmometer, the results show thatthis method can quickly and accurately observed the dam saturation line.
