丹江口水库高水位运行时，其副坝)陶岔渠首枢纽工程存在坝基渗漏及绕坝渗漏问题，需对坝基及坝两岸地基进行渗控处理。通过现场帷幕灌浆试验，根据工程特点制订了合理的地基渗控处理设计和施工方案，最终解决了深厚覆盖层钻进成孔、灌浆孔口管埋设以及土岩接触面灌浆、深厚覆盖层下岩溶强透水岩体灌浆成幕等难题。地基渗控处理完成后进行了工程质量检测和安全监测，结果表明陶岔渠首枢纽工程地基渗控处理满足设计要求，达到预期效果。该工程现场帷幕灌浆试验方法和帷幕灌浆设计、施工方案，可为类似的深厚覆盖层渗控处理问题提供参考。

When the water level is high in the Danjiangkou Reservoir, the following problems occur in its accessory dam - the pivotal project of Taocha Canal H eadw ork, such as seepage in the dam base and around the dam, therefore the seepage control treatment needs to be conducted to the dam base and dam foundation. Based on the field curtain grouting experiment and the project characteristics, a reasonable seepage control treatment design and construction scheme for dam base w as proposed, w hich can solve the follow ing problems including drilling holes in deep overburden layers, burying and covering up grout nipple, grou2 ting at the contact face between the land and rock,and curtain grouting to thehighly permeablekarst rock mass under thedeep overburdenlayers.Afterthecompletionoftheseepagecontroltreatmentfordambase,thequalityandsafetyoftheprojectwere investigated, and the results showed that the seepage control treatment for dam base in the pivotal project of Taocha Canal Headwork meets the design requirements and achieves the desired results. The field curtain grouting experiment method, and design and construction scheme can provide reference for solving similar problems of seepage control of deep overburden layers.
