摘要
This paper discussed the principle and method of the high-density electrical method. Using the high-density electrical method, the authors investigated geological landslide in Chayuangou area of Gaochuan, Sichuan Province. In combination with the borehole data, the position of the main sliding surface, the buried depth of the bedrock, and the water level for landslide were determined, thus providing reliable geophysical basis for tackling the landslide.
