摘要
通过两种试验方法测定对苯板与粗砂的摩擦角。试验结果表明:采用土工合成材料综合测定仪时,随着粗砂含水率的增加,摩擦角、粘聚力的变化规律不强,且苯板产生了变形;采用非散粒体材料摩擦角测定仪时,随着粗砂含水率增加,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 kinds of tests are used to measure the friction angle of the coarse sand and polystyrene board.The test results show that with the increase of moisture content of coarse sand,there are not good regularity with the friction angle and cohesive when using comprehensive geotechnical synthetic materials determination.Meanwhile,the polystyrene board generates deformation.With the increase of percent moisture content of coarse sand,the friction angle has are good regularity when using non-granular mixtures friction angle determination.Meanwhile,the friction angle is basicly unchange.Therefore,the non-granular mixtures friction angle determination is superior to the comprehensive geotechnical synthetic materials determination.
