透明土与标准砂压缩变形特性对比试验研究
Comparative experiments on compressive deformation properties of transparent soil and standard sand
摘要
Abstract
Visualization model tests on internal soil deformation and flow problems by using transparent soil to replace natural soil are gradually recognized and applied. However, the researches focusing on compressive deformation properties of transparent soil manufactured bydifferent methods are relatively little. Based on the twogranular materials of fused quartz and silica gel, one-dimensional compression tests on transparent soil manufactured with different pore fluids, particle size distributions and relative densities are carried out. The test results on Fujian standard sand and Toyoura sand are comparatively analyzed and discussed. At the same time, the internal displacement fields of typical transparent soil under the effect of loading plate are comparatively analyzed. The results show that the compressibility of transparent soil manufactured with sucrose solution pore fluid is relatively closer to that of natural sand than those manufactured with mixed oil and calcium bromide solution pore fluid. The baked quartz is more capable ofmodeling natural sand than the amorphous silica gel. The compressibility of transparent soil is larger than that of Fujian standard sand, especially the transparent soilmanufactured with particle size of 0.5~1.0 mm, which more attention should be paid to.关键词
