摘要
根据三峡二期工程施工揭露的地质、水文地质情况,建立了坝基涌控计算的三维双重介质数值模型.考虑到排水孔间距、方向、深度,帷幕、排水孔的有效性及排水孔的出水能力等众多因素,计算分析、论证了三峡工程坝基渗控方案.结果表明,三峡工程现有设计的坝基帷幕、排水系统是留有余地和安全、可靠的.
Upon the geological and hydrogeologic conditions depicited by the performations in TGP's 2-stage, a 3-D double-porosity model for the calcalutions in seepage control in darn foundation is set up. The projects of seepage control in darn foundation of the Three Gorges Project are analyzed. In the analysis, drainage distance, drainage orientation, drainage depth, drainability, curtain and drainage availability are discussed. The results indicate that the existing curtain and drainage system are safe and effective.
