| 摘 要： | 杨庄截潜工程趾板段建基面以下为弱风化白云岩和含燧石条带白云岩,透水性较强,造成库水漏失严重.为解决建基面以下基岩渗漏问题,采用趾板段帷幕灌浆封堵基岩裂隙而形成防渗帷幕,以减少库水漏失.通过趾板段帷幕灌浆达到封堵基岩裂隙的目的,满足工程设计的防渗要求.

| Abstract: | The rock that under the foundation of toe - slab section of Yangzhuang dam is weak weathered zone of dolomite and flint dolomite with strong permeability, where cause severity seepage of the reservoir. In order to solve the problem of seepage, the curtain grouting were used to block up the fissure of the bedrock, prevent seepage curtain were formed under the toe of dam. The velocity of seepage is reduced to satisfy the requirement of engineering design. |
