摘　　要：巴家嘴水库是一座集防洪、供水、灌溉及发电于一体的大(Ⅱ)型水利枢纽工程。大坝于1958年9月开工兴建,为黄土均质坝。由于多种原因,导致坝体建成近40年来持续不均匀沉陷变形,坝体裂缝几乎年年发生。由于工程质量问题,经评估鉴定,该工程为三类病险危坝,须进行扩容增泄、防渗灌浆等除险加固工作,以满足防洪保坝和供水的要求。Bajiaju reservoir is a large scale（Ⅱ） hydro-junction project with comprehensive functions of flood control,water supply,irrigation and power generation.The dam,which is a loess homogeneous dam,was started construction in September,1958.Because of various reasons,the dam body continued differential settlement in nearly four decades after completion and cracks of the dam occurs almost every year.As the project quality,the result of evaluation and identification showed that it belongs to a third kind of ill and risky dam.Strengthening and eliminating dangers,such as reservoir expansion and discharge increasing,impervious grouting must be carried out in order to satisfy the demand of the flood control and water supply.
