摘要
根据现场取样、室内试验的结果,采用有限元软件Seep/W对吾洞水库坝体在正常蓄水位、设计洪水位、校核洪水位等典型工况下的渗流稳定进行分析与安全评价。计算结果表明:坝体浸润线及出逸点位置较高,出逸点渗透坡降较大,其渗流安全综合评价为C级,存在渗流安全隐患,应及时采取除险加固措施。
According to the results of feld sampling and laboratory tests,using the finite element program Seep/W to analyse the seepage and stability of Wudong Reservoir Dam under the typical condition of the normal water level,the design flood level and flood check level.The results show that the saturation line of the dam is higher,the dam penetration slope is greater,the seepage safety evaluation is C-class,seepage potential safety problems is existing.So the suggestion is reinforcement measures should be taken promptly.
