摘　　要：以宁波轨道交通1号线天童庄车辆段海相软土地基变截面水泥土搅拌桩应用为背景,在变截面桩相关研究的基础上,结合工程中采用的变截面水泥土搅拌桩相关试验,通过将轴对称单桩复合地基数值分析的结果与现场静载试验结果进行对比分析,证明了变截面桩在海相软土地区的适用性,以及设计研究所采用的技术参数、施工应注意的事项等。In this paper,based on the application of variable cross-section cement soil mixing pile in marine soft soil foundation of Tiantongzhuang depot of Ningbo Rail Transit Line 1,this paper proves the applicability of variable cross-section pile in marine soft soil area by comparing the results of numerical analysis of axisymmetric single pile composite foundation with the results of field static load test,based on the relevant research of variable cross-section pile and combined with the relevant tests of variable cross-section cement soil mixing pile used in engineering,and the technical parameters adopted in the design and research,matters needing attention in construction,etc..

关 键 词：变截面搅拌桩 现场试验 技术参数 施工注意事项
