Abstract颗粒级配是影响坝基渗透的重要因素,并影响扬压力的大小和分布特征.采用自制装置对不同颗粒级配的6种土样进行坝基渗透实验和竖向渗透实验,研究了细颗粒含量和最小粒径对坝基渗透和扬压力分布的影响,并建立了细颗粒含量与坝基渗透系数和扬压力之间的关系.研究结果表明:坝基土细颗粒含量30%
Other AbstractGrain composition affects the permeability of foundation soils significantly and has considerable impact on the magnitude and distribution of uplift pressure. In order to study the permeability of the foundation soils and the uplift pressure of a check dam,the vertical and horizontal seepage devices were designed and six groups tests were performed on soils of different grain compositions. The relationships between the uplift pressure and the permeability coefficient/fine content of the foundation soils were established. The results show that the foundation soils are most stable when the content of fine particles(<5 mm) is in the range of 5 30%
