大坝工程防渗灌浆技术及其防渗加固处理措施研究

Research on Seepage-Proofing Control Grouting Technology of Dam Projects and Its Seepage-Proofing Control and Reinforcement Treatment Measures

针对现阶段较为广泛应用的防渗灌浆技术进行了总结与分类,分析了各个防渗灌浆技术的优缺点及适用场景,总结了大坝防渗加固所应考虑的地理环境、工程工艺、大坝材质等条件。以甘肃省张掖市黑河二龙山水电站工程为例,结合水库原始设计资料,针对坝基、坝肩、坝底的防渗加固给出了施工设计方案。

Based on the summary and classification of the anti-seepage grouting technology widely used at present,the advantages and disadvantages of each anti-seepage grouting technology and the applicable scenarios are analyzed,and the geographical environment,engineering technology,dam material and other conditions that should be considered in dam anti-seepage reinforcement are summarized.Taking Heihe Erlongshan hydropower station in Zhangye City,Gansu Province as an example,combined with the original design data of the reservoir,the construction design scheme for the seepage prevention and reinforcement of the dam foundation,abutment and bottom is given.
