摘要
惠州抽水蓄能电站A厂上游水道最大静水头达627 m,高压水道场区水文地质条件极其复杂,场区张扭性断裂较发育,透水性好。在这种地质构造区的高压水道采用钢筋混凝土衬砌,按透水衬砌理念设计国内外尚无成功先例。A厂上游水道充水试验期间出现了较大的渗漏。在高压水道渗漏处理过程中通过摸索、研究,总结出一系列防渗处理技术措施,有效地攻克了强透水性、张扭性地质构造区高压水道防渗处理的难题。
The maximum hydrostatic head for the upstream conduit of Plant A in Huizhou Pumped-Storage Power Station is 627 m. The geological conditions surrounding the conduit are extremely complex, and the rock is good permeability as existing well-developed tension-shear fissures. The conduit was lined with reinforced concrete, and was firstly designed as the characteristics of permeable and anti-crack in China. As the upstream conduit of Plant A emerges larger leakage in the first water filling test, a set of treatments are researched and undertaken, including improving grouting, increasing anchor and plugging the exploratory tunnel. The treatment is successful.
