摘　　要：以珠三角水资源配置工程中的两个工作井施工为例,通过采用先进的铣槽机设备、护壁泥浆配比优化及分节吊装技术等方法,成功解决软弱地层条件下的超深地连墙施工存在的槽壁坍塌、垂直度控制难和钢筋笼吊装困难三大施工难点。施工效果分析表明此方案下的施工质量高、效果好,可为类似条件下的施工提供技术参考和实践指导。Taking the construction of two working shafts in the Pearl River Delta Water Resources Allocation Project as an example,by adopting advanced trenching machine equipment,optimizing slurry ratio for wall protection,and sectional hoisting techniques,the three major construction challenges of trench wall collapse,difficulty in verticality control,and reinforcement cage hoisting under weak strata conditions during ultra-deep diaphragm wall construction were successfully resolved.Analysis of the construction results shows high quality and effectiveness,offering technical reference and practical guidance for construction under similar conditions.
