| 摘 要： | 研究目的:锦屏二级工程地质条件复杂,4条长达17 km的引水隧洞具有超埋深,大直径特点。为更全面分析锦屏二级隧洞围岩渗流特性,采用有限元方法,建立渗流简化模型,重点研究深埋引水隧洞不同条件下的渗流场特征。研究结论:研究表明,不同灌浆圈厚度及渗透性对围岩渗流特性影响较小,运行期施工排水洞及A,B线辅助洞封堵会引水隧洞围岩渗压增加明显;成果可为锦屏二级深埋隧洞的设计及施工提供参考依据。

| Abstract: | Research purposes: The geological conditions are complex in the area of the Jinping second level power station and there are four tunnels with 17km length,extreme burial-depth and large diameter.A simplified seepage model is established with FEM for the surrounding rock mass of tunnels in order to mainly research the seepage characteristics of the tunnel under the different conditions. Research conclusions: The results show that the seepage characteristics is less influencd by grouting circle thickness and ... |
