摘　　要：基于水阳江船闸基坑工程施工情况和监测成果,对单排桩在软土基坑支护中的应用进行了分析。为研究单排桩的安全性,对支护方案抗倾覆和整体稳定进行验算,通过计算获得了支护结构的桩顶水平位移和冠梁后缘地表沉降。对比计算结果和现场监测成果表明:现场监测的桩顶水平位移接近计算位移,地表沉降大于冠梁沉降,计算结果可以指导设计、施工。Based on the construction and monitoring results of Shui-yangjiang ship lock foundation pit project,the application of single row piles in soft soil foundation pit support is analyzed.In order to study the safety of single row piles,the anti over turning and overall stability of the support scheme are checked.Through the calculation,the horizontal displacement of the pile top of the support structure and the surface settlement at the trailing edge of the crown beam are obtained.The comparison of calculation results and field monitoring results shows that the horizontal displacement of pile top monitored on site is close to the calculated displacement,and the surface settlement is greater than the crown beam settlement.The calculation results can guide the design and construction.
