摘　　要：鞍子坝库岸的主要破坏形式是由于库水位消涨而使岸坡产生的塌岸。应用土工格栅加筋土护坡和土工石笼护脚相结合的方法进行库岸防护设计,且对于多级斜坡式加筋土挡墙的稳定性验算作了一些初步的探讨。The main destroy form of the reservoir bank was bank collapse. Hereby, this paper primarily method implementing the design work of defending reservoir bank by combing the preventing slopes using geo-textile and preventing toe using gabion. to implement the design work of defending reservoir bank. The four steps reinforced earth retaining wall with panel was used in the design. By consulting the codes such as standard for application of geo-synthetics in hydraulic and hydro-power engineering （SL/T225-98）, standard for design of reinforced earth engineering in road , using Coulomb soil pressure, to check the design in exterior stability（including foundation bearing capacity, anti-slipping stability and anti-capsize stability） and internal stability （including the geo-textile strength and anti-lift stability）
