Abstract: A slope of a power plant is located in the II and IV-class terraces of Yellow River; its maximum height is 55 m. The slope is composed of Pleistocene loess, silt, sand and gravel layer and lower Pleistocene pebble gravel layers. The basic earthquake intensity of the site is 8-magnitude. The loess has collapsibility. The construction of the power plant and the operation of cooling towers and other buildings will make the moisture content of the soil have a certain increase. Contrapose the features of the slope, mechanical parameters of soil under multi-rate of water content are obtained through investigation, multi-working conditions are chosen for the slope design. Only based on the understanding of the slope characteristics and deformation and failure mode, selecting suitable parameters of reasonable working conditions, can the slope design meet the engineering practice, and achieve safe reasonable, economical and applicable

Key words: high slope, parameter selection, working condition selection, slope treatment
