First, a simple test of moisture content, natural density and clay content is carried out on a fresh section of the moraine soil accumulation body, and then the void ratio, compression index, shear strength, compressive strength, Permeability and expansibility and other relatively complex engineering mechanics indicators, so that the preliminary evaluation of site stability can be quickly carried out; and then according to the evaluation results, targeted selection of dangerous sites for detailed investigation. Compared with the previous technology, the present invention can save the construction period of exploration and evaluation, reduce the types and procedures of parameter testing, and reduce economic costs. Significant applicability advantages.
