摘　　要：大梁水库是修建在湿陷性黄土基础上的大坝,该地区黄土具有遇水失陷、液化以及渗漏等特点,相应大坝基础具有沉降、渗漏等问题。为确保建筑物安全,减小基础沉降、减少渗漏,经多年的分析、研究、计算及专家论证,采取了适合本工程特点的处理措施。大梁水库基础处理涵盖了:高喷防渗、塑性混凝土防渗和帷幕灌浆;坝体心墙黄土防渗;针对液化采取了压重处理等诸多方案。Daliang reservoir is a dam built on collapsible loess,the loess in this area is characterized by collapse,liquidation and leakage under the influence of water and the dam foundation has problems of settlement and leakage correspondingly.In order to ensure the safety of buildings,reduce foundation settlement and leakage,after years of analysis,calculation and experts' demonstration,appropriate measures suitable for the project features are taken.The foundation treatment measures include high-pressure jet grouting,plastic concrete anti-seepage and curtain grouting;the dam core adopts loess seepage control;and overburden treatment is taken for the liquefaction problems.
