摘　　要：文章论述了鹊山水库除险加固工程建设的必要性及防渗范围,通过比较多种防渗工艺的优缺点,结合鹊山水库的实际情况,最终选定了高压喷射灌浆防渗墙工艺。该工艺可满足水库坝体及地基的防渗要求,无需对坝顶进行加宽便可满足施工需求,且施工时无需大规模开槽,更适合鹊山水库无法排空的施工条件要求。This paper discusses the necessity of the Queshan Reservoir strengthening works and the scope of seepage prevention.By comparing the advantages and disadvantages of various seepage prevention technologies,and combined with the actual situation of Queshan Reservoir,the high pressure jet grouting seepage prevention wall technology is finally selected.The technology can meet the impervious requirements of dam body and foundation,as well to meet the construction requirements without widening the dam crest,and the construction does not need large-scale slotting,which is more suitable for the construction conditions of Queshan Reservoir for non-emptied.
