云南病险水库普遍存在坝体和坝基渗漏严重的问题,以白鹤水库除险加固工程为例,探讨了高压喷射灌浆技术在大坝防渗加固中的应用及效果.水库防渗处理后坝体浸润线降低,下游坝坡原渗水潮湿现象消失,高水位时下游坝脚的渗水量也大幅减小,坝体和坝基的防渗性能明显改善.高压喷射灌浆技术适用范围广,施工简便灵活,质量检测方便,对其他病险水库的加固处理具有借鉴作用.%The ill-conditioned reservoirs in Yunnan Province commonly have severe seepage problems in the dam body and foundation. By taking the reinforcement of Baihe Reservoir as an example, the application and effectiveness of high-pressure sprinkling grouting technology in anti-seepage and reinforcement of dams in Yunnan Province are investigated. The results show that the phreatic line of the dam body decreases after anti-seepage treatment of Beihe Reservoir. The phenomenon of leakage on the downstream dam slope disappears. The leakage quantity at the downstream dam toe greatly decreases at high water level. The anti-seepage properties of the dam body and foundation are obviously improved. The high-pressure sprinkling grouting technology has wide range of applicability, its construction is simple, and its quality inspection is convenient. It is helpful to the reinforcement of other ill-conditioned reservoirs.
