桶基在粉土中负压沉贯过程的试验研究

Research on experiment of tub base in power soil negative pressure sinking process

主要通过模型试验对粉土中负压沉贯过程的失稳机制进行了研究,并探讨了不同比尺桶基的沉贯效应,根据模型试验结果对不同比尺桶基的沉贯行为进行了论述,并初步分析了沉贯行为效应产生的原因。

This paper study instability mechanism by the model test of the silt in the suction penetration process, and to explore the barrel of the penetration effects in different scale. According to model test results studied different scale of the barrel of the penetration effects, and pre-liminary analyzed cause of the penetration effects.
