各类土的特征及取样试验方法，岩土人必备！知乎专栏

一、粉质粘土定义：塑性指数大于10且小于或等于17的土应定名为粉质粘土，肉眼观察，细土中有砂粒，干时不坚硬，用锤可打成细土粒，湿时有塑性有粘结力，能搓成φ052mm 2、含碎石的粉质粘土，应该是以粉质粘土为主，含5～50%的碎石，粒径一般以20mm以上为主。 ,% *Jm 3、碎石土是指粒径大于20mm的颗粒含量超过50%的土，粒径大于2mm的含碎石粉质粘土？岩土工程勘察 Powered by phpwind2020年10月2日如果是刚形成的，那和含碎石粉质黏土太好区别了，细颗粒比例不足，分布曲线也不是那么自然，细到极细颗粒的分布肯定不均匀而且少。不论是镜下还是用手搓碎石土和含碎石粉质粘土如何区分？知乎粉质粘土；潮湿的黄土；夹有碎石、卵石的砂；粉质混卵（碎）石；种植土、填土: 06~08: 1100~1600: 用锹、锄头挖掘，少许用镐翻松: 三类土（坚土） Ⅲ: 软及中等密实粘土；重工程土分类依据原则是什么？知乎粉质粘土稍湿，可塑（硬塑），主要由粘粒组成，土质较均匀，粘性较强，含少量粉粒，（无摇振反应，切面光滑（粗糙），稍有（无）光泽，干强度、韧性中等）。坡（洪岩石及土的分类知识讲解，你会分辨了吗？知乎专栏

4、泥质胶结：由粘土类矿物组成，颜色不稳定，胶结松散。碎屑岩类岩石按颗粒大小分为： ☆砾岩(角砾岩)直径大于2mm、含量大于50%；☆砂岩直径201mm、含量大粉质粘土（silty clay）是据GB500072011规范，塑性指数介于10～17之间的黏性土；或按水利电力部1962年规程，粘粒含量30%～50%，且粉粒组含量大于砂粒组含量的粘土。粉质粘土百度百科含碎石粉质粘土成因是风化壳经过外力搬运作用。粉质黏土从成因上看应定为红粘土,特指灰岩地区的风化壳,是一种具有高粘性的、可能带有膨胀性的、上硬下软特征的特殊粘土,粉含碎石粉质粘土是什么百度知道三类土是指粘土或冰粘土、重壤土、粗砾石、干黄土或掺有碎石的自然含水量黄土等，土的坚固系数为0．811．0，须用尖锹并同镐开挖。（四）四类土四类土是指硬粘土、含碎三类土百度百科2017年3月18日由于所研究的碎石土为稍密状态下含粉质粘土碎石，粗粒含量较高，相对于细粒含量高的粘性土以及粒径小的碎石土，含水率变化不会引起其颗粒结构、大小及密含水率和颗粒级配对稍密碎石土抗剪性能及地基承载
