Abstract: Through the systematic investigation of an informal waste landfill in northern North China， the relevant geological data of the site area and the physical property test results of the laboratory test were carefully collected，and the buried depth，shape and volume of the waste in the site area were investigated by using the method of combining high-density electrical method with engineering survey，and a three-di⁃ mensional geological model was established.The study results can provide reference for the landfill composi⁃ tion，volume investigation and related environmental management of the same type of landfill.

Key words: landfill area, high density electrical method, garbage volume, three-dimensional geologi? cal mode
