摘　　要：水利除险加固对于早期建设的许多病险水库安全运行至关重要。沙表北水库建成年代早,影响水库安全稳定的工程地质条件复杂,同时坝体存在安全稳定隐患,有渗流安全隐患。以沙表北水库为研究背景,从坝顶加固、防渗加固和坝坡加固提出系统加固方案,针对大坝渗流和安全稳定进行复核分析,提出合理的监测补充措施。The reinforcement of water conservancy is crucial for the safe operation of many dangerous reservoirs constructed in the early stages.Shabiao North Reservoir was built early,and the engineering geological conditions that affect the safety and stability of the reservoir are complex.At the same time,there are safety and stability hazards in the dam body,including seepage safety hazards.Taking Shabiao North Reservoir as the research background,this paper proposes a systematic reinforcement plan from the aspects of dam crest reinforcement,anti-seepage reinforcement,and dam slope reinforcement.A review analysis is conducted on the seepage and safety stability of the dam,and reasonable monitoring and supplementary measures are proposed.
