摘　　要：输水渠道渗漏时有发生,对渠坡衬砌表面涂刷丙烯酸水泥防水涂料进行防渗封堵后,仍有少量渠水出逸。论文针对反复产生的渗漏问题,采用现场检查及钻探取样等方式,结合渠基的地质条件、渠堤的施工情况和防渗体的防渗情况,综合分析产生了渗漏的主要原因是存在绕渗现象,渗漏渠水从未防渗封堵段绕流到防渗封堵段。同时针对渗漏原因提出了防治绕渗与加固堤脚两类处置措施。Leakage occurs in the water supply channel,and after applying acrylic cement waterproof coating to the surface of the channel slope lining for anti-seepage sealing,a small amount of channel water still escapes.The paper focuses on the repeated leakage problem,using on-site inspection and drilling sampling methods,combined with the geological conditions of the canal foundation,the construction situation of the canal embankment,and the anti-seepage situation of the anti-seepage body.It comprehensively analyzes that the main reason for the leakage is the existence of seepage diversion,and the leakage canal water flows from the non seepage blocking section to the seepage blocking section.At the same time,two types of disposal measures were proposed to prevent seepage and reinforce the embankment foot.
