| 摘 要： | 大箐水库由于近期的两次强烈地震对其造成了严重破坏。最主要的问题是坝体、坝基和坝肩渗漏都较严重。排水棱体大部分被耕植土覆盖,排水不畅;棱体上部坝坡脚大面积浸水,通过渗流观测资料分析和渗流有限元计算分析,全面评价了大箐水库大坝的渗流安全状况。结果表明:坝基、坝坡在所有工况下的计算水力坡降均小于其允许水力坡降,故现状是大坝暂不会出现渗透变形。大坝渗流安全评价为C级,建议采取相应防渗处理措施并完善防渗体系。

| Abstract: | Daqing Reservoir due to the recent two strong earthquake on the Daqing Reservoir caused serious damage.The main problem is the dam body,dam foundation and dam leakage are more serious.Most of the drainage prism is covered by the cultivated soil,and the drainage is poor.The upper part of the slope is flooded with large area,and the seepage safety condition of Daqing reservoir dam is evaluated comprehensively by analyzing the seepage observation data and finite element analysis.The results show that the calculated hydraulic slope of the dam foundation and dam slope is lower than that of the hydraulic slope.Therefore,the dam can not be infiltrated.Dam seepage safety evaluation for the C level,it is recommended to take appropriate anti-seepage treatment measures and improve the seepage control system. |
