淤泥中的负孔隙水压力则较小，其数值大小主要取决于所处位置的软土特性。
But the negative pore water pressure in the soft soil is smaller, which is decided by the geologic characteristics of the soft soil.
同时根据原型试验结果，研究了负孔隙水压力对抗拔承载力的影响，确定了其值的大小。
Furthermore, the effect from the negative pore water pressure on the uplift bearing capacity is investigated in the light of the result of the prototype test, of which the value is determined as well.
在非饱和土条件下产生的负孔隙水压力（基质吸力）对于预测如边坡、挡土墙、挖方工程、基础工程之类的土石结构的稳定性十分重要。
Unsaturated soil condition which give rise to negative pore pressure is important in evaluating the stability of geotechnical structures such as slopes, retaining walls, excavations and foundations.
