摘要
结合现场踏勘及室内土工试验成果,采用有限单元法对六岭水库坝体在正常蓄水位、设计洪水位、校核洪水位等工况下的渗流稳定进行了分析与安全评价。渗流分析结果表明:坝体存在较大渗流安全隐患,其渗流安全综合评价为C级,应及时采取坝体心墙灌浆、重建排水棱体等加固措施。
Based on the results of site exploration and indoor geotechnical tests,seepage analysis and safety appraisal for the main dam of Liuling reservoir were conducted with finite element method under several typical water level conditions,including normal pool level（NPL）,design flood level and check flood level.The results of seepage analysis demonstrate that there exists considerable hidden trouble in dam body with a comprehensive safety appraisal conclusion of grade C.Reinforcement measures are required including core wall grouting and reconstruction of drainage prism etc.
