摘要
Abstract
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.关键词
