【摘要】 惠州抽水蓄能电站A厂上游水道高压隧洞内径为8.5 m,最大静水头为624 m,PD值(水头×直径)值达5304Tm,为我国目前最大PD值的高压钢筋混凝土隧洞,其设计采用了透水衬砌理论。对惠州抽水蓄能电站A厂上游水道的工程地质条件、布置、结构设计、充水试验及处理、监测成果及分析、安全复核等作了介绍。总结分析表明,高压岔管及高压隧洞受力条件良好,处于安全状态;水道渗漏量正逐步减小。更多还原

【Abstract】 The high-pressure tunnel of the upstream conduit of Plant A in Huizhou Pumped-Storage Power Station with a diameter of 8.5 m and a maximum hydrostatic head of 624 m,it has a maximum PD of 5304 tm in China,and is designed with permeable lining.The geological conditions,layout,structural design,water-filled tests and treatment,monitoring results and safety of the upstream conduit are reviewed.The results show that the stresses of high-pressure tunnel and bifurcation are in good conditions and the leakage of conduit is gradually decreased.更多还原
