Through utilizing the experimental means, as designing model bucket foundation and suction penetration operation process,making up silty sand soil,installing sensor for pore water pressure,and from the direction of the disruptive soil body,the variational relations among .
该设计通过配土、设计模型桶基和负压沉贯的操作过程、设置孔压传感器等实验手段 ,努力从土体破坏的角度 ,寻求负压沉贯过程中沉贯负压、沉贯阻力及孔隙水压力之间的变化关系和确定桶基的上拔力。
