In the construction of large-scale hydropower stations, a large amount of waste slag is produced and is often deposited in the nearby site, thus forming a large scale waste accumulation body. Under the condition that the thickness and trend of the slag accumulation body are not ascertained, the excessive heap load will easily cause the collapse accident, so it is very important to investigate the distribution of the slag accumulation body. In this paper, the high density resistivity method was used as the main method, and the high density resistivity method was used to verify the abnormal area and key position of the electrical method. At the same time, drilling holes were arranged at the site for comparative analysis. The results show that the high density electrical processing results are in good agreement with the results of transient Rayleigh surface wave method and borehole data. Through this investigation, the authors basically detected the distribution of abandoned slag deposits. High density electrical method and transient Rayleigh surface wave method are effective methods for investigating slag deposits.
