孔隙液体对透明土渗透特性影响对比试验
Contrast experiments on permeability of transparent soil influenced by pore fluids
摘要
Abstract
Transparent soil is widely used for visualization of physical model tests on internal soil deformation engineering problems.Based on the transparent soil materials manufactured by fused quartz and three typical pore fluids (mixed oil,calcium bromide solution,and sucrose solution),a group of constant head permeability tests were carried out.Considering the difference between pore fluid and penetrating liquid,the permeability coefficients influenced by different pore fluids,particle size distribution,and relative density were measured in detail.Water infiltrations through transparent soil manufactured by different pore fluids were also measured.The penetration test on China ISO standard sand was taken for comparative analysis.Then,electro-osmosis visualization model tests were carried out based on transparent soil samples manufactured by different pore fluids.The influence of pore fluid on electro-osmotic process and mechanism is preliminary discussed.It shows that the permeability of transparent soil are not only related to particle size distribution and relative density,but also related to the pore fluids.Permeability coefficient of transparent soil manufactured by mixed oil or calcium bromide solution is the closest to that of natural sand.关键词
