摘　　要：邵伯闸是南水北调东线工程输水线路上的涵闸,已严重老化。为防止在加固改造过程中出现地基液化的情况,采用局部灌浆的方法对其进行加固。本文针对邵伯闸地基土在局部灌浆前后的液化特性进行振动三轴试验,并进行数理分析,研究表明局部灌浆可以有效防止节制闸地基土的液化,为其他节制闸改造加固工程提供借鉴。Shaobo Sluice is a sluice gate on water conveyance line of South-to-North Water Diversion East Line Project, which has been aged seriously. Local grouting method is adopted for consolidation in order to prevent foundation liquefaction possibility during the reinforcement process. In the paper, vibration triaxial experiment is carried out aiming at the liquefaction characteristics of Shaobo Sluice foundation soil before and after local grouting. Foundation soil liquefaction problem is studied mathematically, thereby providing reference for other regulating sluice transformation and reinforcement projects.
