黄河阶地上某电厂高边坡参数选取及其工程治理

某电厂边坡位于黄河II、IV级阶地之间，最大高度达55 m，主要由上更新统黄土、粉土、砂砾石层及下更新统砂砾卵石层组成。厂址地震基本烈度为Ⅷ度；黄土具有湿陷性；电厂施工及冷却塔等建筑物运行后会对土体的含水率有一定的增加。针对边坡的工程特征，在勘察中获取了多种含水状态下的土体力学参数，在多种工况条件下对边坡进行治理设计。分析认为，在掌握边坡特征和变形破坏模式基础上，选取合理的参数、合适的工况，对边坡进行治理设计时才能符合工程实际，做到安全合理、经济适用

Treatment and parameter selection of high slope of a power plant located in the terraces of Yellow River

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.
