| 摘 要： | 粤连电厂贮灰场堆石面板坝发生了较大渗漏,危及灰坝安全运行。经对灰坝进行渗水检查和分析,找出了渗漏位置主要分布在坝踵50 m范围。为了保证灰坝安全运行,提出了灰坝低水位运行和坝前冲填堆粉煤灰治理措施。实践证明坝前冲填堆灰治理渗漏十分理想,目前渗漏已经得到根治,并节约了大量渗漏治理费用。

| Abstract: | Serious leakage occurred in the rock-faced dam for the ash disposal area in Yuelian Power Plant and endangered the safety ofthe dam.Upon inspection and analysis of the leakage,it was found that the leaking spots were mainly distributed within 50 m of thedam heel.To ensure the safety of the dam,countermeasures including low water-level operation of the dam and sluicing-siltationmethod with coal ash in front of the dam were presented.Practical results showthat the sluicing-siltation method with coal ash in frontof the dam is very effective.At present,the leakage has been rooted out and a large sum of money for leakage treatment has beensaved. |
