摘要
将内水压力以体力的形式作用于隧洞衬砌和围岩,建立了高压隧洞内水外渗渗流场与应力场的耦合数值分析的计算模型。该计算方法较好的反映了水工高压隧洞的内水外渗后实际受力变形情况。将其应用于惠州抽水蓄能电站高压隧洞不同方案的对比计算研究,得出了一系列有意义的结论。
The inner water pressure is applied to the lining block and surrounding rock as physical force, and the coupled analysis model of seepage field and stress field is formed. The calculation method can preferably reflect the actual stress and strain situation of hydraulic tunnel with high pressure with seepage from inner tunnel to outer tunnel. It is applied to the comparing research for the tunnel with high pressure water in Huizhou Pumped Storage Power Station, and a series of conclusions is drawn.
