摘　　要：针对深圳赤坳水库主浆砌石大坝存在的整体抗滑稳定安全裕度不足以及左坝肩存在渗漏的问题,结合工程工程特点,提出了“浆砌石-混凝土”组合坝的新型大坝结构加固技术,设计了2种不同的浆砌石-混凝土组合坝体加固方案(坝前防渗加固和坝后培厚加固),并对2种加固方案进行了抗滑稳定及防渗效果分析评估。结果表明2种方案均满足相关规范要求。The main masonry dam of Chi ao Reservoir in Shenzhen faces insufficient overall anti-sliding stability safety margin and leakage of the left dam abutment.In view of these problems,this paper proposed a new reinforcement technology for a composite dam of mortar masonry-concrete based on engineering characteristics and designed two different reinforcement schemes for the composite dam of mortar masonry-concrete,such as anti-seepage reinforcement before the dam and the thickening reinforcement after the dam.Furthermore,the paper evaluated the anti-sliding stability and anti-seepage effect of the two schemes.The results show that both schemes meet the relevant specification requirements.
