Hydraulic gradient in silt increases then decreases and the maximum is occurred near the edge of the bucket . Hydraulic gradient in sand increases constantly and the maximum is occurred when the bottom of bucket arrives to the sand surface.
计算出砂中和粉土中不同传感器间水力梯度的大小，揭示了负压沉贯过程中水力梯度随时间和深度的变化过程，粉土水力梯度先增大后减小，极大值产生桶端附近；砂中水力梯度一直增大，极大值产生在桶底接触砂面时。
