石家庄市区第一层砂土室内试验研究

Experimental Study on the First Layer of Sands in Shijiazhuang City

砂土作为散体材料具有不容易采取原状试样、采取试样的成本高、采取难度大等特点,并且缺乏相关方面的室内试验经验。通过含水率试验、密度试验、颗粒分析(筛析法)试验、休止角试验及直接剪切试验(快剪)对砂土的物理性质及抗剪强度指标进行了研究,并提出了相应的建议取值。

As the bulk material, sand is not easy to take the original sample, take the sample high cost, take the sample difficulty and so on, and lack the relevant laboratory test experience. In this paper, the physical properties and shear strength indexes of sand are studied by water content test, density test, particle analysis(sieve analysis) test, repose angle test and direct shear test(quick shear), and the corresponding fitting equations and suggestions are put forward.
