摘　　要：刃脚土阻力和侧壁土压力的大小和变化规律对沉井是否能平稳下沉具有重要影响。为此,以深厚软土地区圆形沉井为研究对象,通过布置刃脚踏面、刃脚斜面、沉井侧壁土压力传感器,对沉井整个施工过程展开现场监测试验,分析现场监测数据,得出土压力的分布及变化规律,并与理论和规范计算进行对比。The size and variation of soil resistance of blade foot and soil pressure on sidewall have an important influence on whether the caisson can sink smoothly.For the above,taking the circular caisson in deep soft-soil area as the research object,by arranging earth pressure sensors for tread surface of the blade foot*slope of the blade foot,and side wall of the caisson,the field monitoring experiment is carried out on entire construction process of the caisson,and the field monitoring data is analyzed*the distribution and change law of earth pressure is derived,and it is compared with theoretical and normative calculations.
