【摘要】 通过5个不同材料及其大小的桶基在粉土中的负压沉贯实验测定桶基内不同深度处孔隙水压力的产生和发展,计算出桶基作用下粉土中渗流梯度的大小,揭示出负压沉贯过程中渗流梯度的变化过程,表明土体在沉贯前后性质的变化,为桶基的设计提供依据。更多还原

【Abstract】 Pore water pressures were measured at different depths during penetration by suction of five buckets with different material and size in the silt, the hydraulic gradients in the silt were calculated. Changing process of the hydraulic gradient was shown during penetration by suction. The results of the experiments showed changing of the silt property after penetration, this should be considered for the design of the buckets.更多还原
