摘　　要：针对石水坑水库的坝坡稳定性和防渗加固问题展开研究,通过对水库大坝的迎水坡与背水坡现状、坝体可能存在渗漏和压实性较差等分析,揭示了存在的安全隐患和加固需求。此次设计了灌浆加固、护面修复等加固方案,并采用《水工结构有限元分析系统(AutoBANK)》的程序进行计算,对不同工况下的稳定性进行分析,选定了计算断面和工况,对加固方案的可行性与效果进行了分析。研究结果表明,加固方案在提升水库坝坡稳定性和防渗效果方面具有显著成效,为水库的安全运行提供了科学依据。This study focuses on the stability and anti-seepage reinforcement of the dam slope of Shishuikeng Reservoir.By analyzing the current situation of the upstream and downstream slopes of the reservoir dam,as well as the possible leakage and poor compaction of the dam body,the existing safety hazards and reinforcement needs were revealed.This paper designs reinforcement schemes such as grouting reinforcement and protective surface repair,and uses AutoBANK program for calculation to analyze the stability under different working conditions.The calculation section and working conditions are selected,and the feasibility and effectiveness of the reinforcement scheme are analyzed.The research results indicate that the reinforcement scheme has significant effectiveness in improving the stability and anti-seepage effect of the reservoir dam slope,providing a scientific basis for the safe operation of the reservoir.
