根据江口水电站坝基主要工程地质条件 ,系统介绍了坝基开挖及加固处理的设计思想 ,开挖基本设计原则为满足拱坝体形设计要求 ,大坝基础开挖采用径向开挖 ,不同高程控制点直线连接 ,保证满足大坝轮廓的要求 ,并方便施工。两岸坝肩O21n页岩部位根据风化情况局部掏挖 5～ 8m深 ,并往下游扩挖 4m左右 ,再作混凝土回填处理。并对基础加固处理措施与方法作了较详细的阐述
According to the main engineering geological conditions of dam foundation of Jiangkou hydropower station, the design idea of excavation and reinforcement of dam foundation is systematically introduced. The basic design principles of excavation are to meet the design requirements of arch dam. Radial excavation, different elevation control Point straight line connection to ensure compliance with the requirements of the dam profile and facilitate the construction. According to the weathering conditions, some sections of O21n shale on both sides of the dam should be excavated 5 ~ 8m deep and expanded 4m downstream to make concrete backfilling. The basic reinforcement measures and methods are described in more detail
