摘　　要：分析了那吉航运枢纽工程发电厂房尾水渠右岸挡土墙的地质条件,针对挡土墙挡土高度大、基础地质条件差的特点,通过方案比较,采用混凝土衡重式挡土墙结构,应用材料力学方法对挡土墙进行抗滑、抗倾覆、应力分析,确定了挡土墙最佳断面型式。An analysis was made on the geological conditions of the right bank earth-retaining wall at the powerhouse tail channel of Naji Navigation Complex. In view of the characteristics of the earth-retaining wall including great height and poor foundation geological conditions, counter-weight concrete earth-retaining wall structure was determined by scheme comparison. Based on an analysis of the sliding resistance, safety against overturning and stress of the earth-retaining wall made by material mechanics method, the optimum cross section type was determined for the wall.

关 键 词：那吉航运枢纽工程 衡重式挡土墙 稳定分析 最佳断面
