摘要
水库防渗加固的质量直接关系到大坝的安全运行和生命周期。基于某水库扩建工程,根据坝址周围分布的岩层特性和现有大坝的坝体材料性质,初步拟定了三种坝体防渗方案,根据地形地质条件,工程施工和经济投资等参数充分比选,确定粘土斜墙风化料坝Ⅰ方案为最优设计方案,最后进行了该方案的防渗能力校核,结果表明防渗设计满足水库扩建工程要求。该方案优化了坝体结构,节约了建设用地,可为其他工程扩建及除险加固设计提供参考。
The quality of reservoir anti-seepage reinforcement is directly related to the safe operation and the life cycle of the dam.Based on the expansion project of a reservoir,three dam anti-seepage schemes are preliminarily formulated according to the rock strata characteristics around the dam site and the material properties of the existing dam body.Considering the some parameters such as topographic and geological conditions,construction and economic investment and so on,the clay inclined wall weathering material dam Ⅰ scheme is determined as an optimal anti-seepage scheme.The anti-seepage capacity of above scheme is proofread.The results show that the anti-seepage design meets the requirements of reservoir expansion project,which optimizes the dam structure and economizes the construction land.The experience can provide a reference for other engineering expansion and reinforcement design.
