摘要
通过两种试验方法测定苯板与细砂的摩擦角。试验结果表明:采用土工合成材料综合测定仪时,随着细砂含水率的增加,摩擦角、粘聚力的规律性不强,且苯板产生了变形;采用非散粒体材料摩擦角测定仪时,随着细砂含水率增加,摩擦角基本不变,规律性较好。非散粒体材料摩擦角测定仪优于土工合成材料综合测定仪。
Two ways of test were used to measure the friction angle of the fine sand and polystyrene board. The test shows: With the increasing of percent moisture content of fine sand,there are not good regularity with the friction angle and cohesive when use the instrument of comprehensive geotechnical synthetic materials. At meantime,the polystyrene board generated deformation. With the increasing of moisture content of fine sand,there are good regularity with the friction angle when use non granular mixtures friction angle instrument,at meantime,the friction angle is basicly unchangeable. Therefore,the instrument of non granular mixtures friction angle is superior to that of comprehensive geotechnical synthetic materials.
