Abstract: In recent years, the research on the influence of surfactants on the mechanical and environmental geotechnical properties of loess and bentonite has become the focus of environmental geotechnical field. Based on this, this paper proposes a mechanical analysis model of loess and bentonite based on the mixed washing leapfrog algorithm, and studies the influence of surfactant on the mechanical and environmental geotechnical properties of loess and bentonite and its quantitative evaluation. Firstly, the data of mechanical strength, composition change, permeability, density change and load-bearing change of loess after adding surfactant are analysed, and then the comprehensive comparative analysis and evaluation of environmental geotechnical characteristics with or without surfactant are carried out by using the mixed washing frog leaping algorithm. Finally, the mechanical analysis model is verified by design experiment. The results show that the mechanical analysis model of loess and bentonite based on the mixed washing leapfrog algorithm has the advantages of high feasibility, high data accuracy and high analysis efficiency, which can realise the quantitative evaluation of the influence of surfactants on the environmental geotechnical characteristics.
