摘　　要：在投资有限的前提下,布设少量钻孔、结合现场调查了解,基本查清了大石洞水库存在坝体、坝基、右坝肩严重渗漏、大坝防洪能力不足且溢洪道基本不具备泄流能力、输水底涵洞身严重渗漏且结构破损等主要病险。经技术经济比选,采用坝体充填灌浆,坝基、右坝肩帷幕灌浆,回填原溢洪道、新建溢洪道,拆除输水底涵和二涵、新建输水涵洞,增设安全监测设施等加固处理方案,较合理地消除了水库病险。On the premise of limited investment, it arranges few boreholes, combined with field investigation it found out that Dashidong reservoir which has major problems such as dam foundation and right dam abutment seepage seriously, the dam’s flood control ability is insufficient and the spillway has no discharge capacity basically, the water conveyance culvert seepage seriously and the structure has been damaged and so on. By the calculation, analysis and scheme comparison, it use filling grouting of the dam body, curtain grouting of the dam foundation and right abutment, backfilling of the original spillway and building a new spillway, removal of culvert at the bottom of the dam and culvert No.2, building a new culvert at the same time, increase of safety monitoring facilities and so on, which reasonably solved the dangerous problem of reservoir. The corresponding design has certain reference significance for similar engineering treatment.
