摘　　要：针对西山水库坝址区存在单薄垭口、岩体渗透性强、岩石裂隙较发育等不利地质条件,可能给大坝安全稳定带来不利影响的问题。结合坝址区地质条件,从坝型适应性、枢纽布置、施工条件、综合投资等方面,对坝型和坝体结构体型等关键内容进行详细论证分析。设计优选的混凝土砌毛石重力坝方案,具有枢纽布置紧凑、填筑体量小和综合投资省等优点,且坝体应力及抗滑稳定安全系数均满足规范要求,设计方案合理、可行。The adverse geological conditions such as thin pass,strong rock permeability and relatively de⁃veloped rock fissures which may have an adverse impact on the safety and stability of the dam have ex⁃isted in the Xishan reservoir dam site area.Combined with the dam site area′s geological conditions,the dam type and dam structure and other key contents have been demonstrated and analyzed in detail from the aspects of dam type adaptability,hub layout,construction conditions and comprehensive investment.The optimized concrete rubble gravity dam scheme with the advantages of compact hub layout,small floor area and low comprehensive investment,and the dam stress and anti sliding stability safety factor can meet the specification requirements is reasonable and feasible.
