【摘要】 在阅读、分析以往的有关资料的基础上 ,结合实际的试验条件 ,对桶形基础及其作用下的粉质土海床失稳机制研究的试验作出了专门设计。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。并且指出了数据处理的基本思路 ,以利于课题的深入研究。更多还原

【Abstract】 On the basis of reading the relevant data and combining the practical experiment condition, the experiment of bucket foundation and unstability mechanism research influenced by bucket foundation on silty sand seabed were specially designed.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 penetration suction pressure,penetration resistance and pore water pressure were strenuously searched. Besides those, the basic thinking way of data processing was pointed out,which was in favor of deep research.=更多还原
