利用锥沉深度测定液性指数的方法

A Way of Acquiring Liquidity Index by Cone Penetration Depth

对于粘性土液性指数,传统做法是:通过测试天然含水率和液、塑限含水率,然后利用公式计算得到液性指数;本文依据液、塑限联合测定法基本理论,事先建立液性指数和锥沉深度关系曲线,在实际工作中,对符合要求的试样,通过测定锥沉深度,在关系曲线上查得相应的液性指数。

In order to acquidity the liquidity index of clay soil,people usually measure its moisture ratios under natural status,liquidity limit and plastic limit,and then calculate the value of liquidity index by known formulas. In this paper,the author presents a new way of getting liquidity index of clay soil by cuive,which reveals the relationship between liquidity index and cone penetration depth,and this method can be widely used in practical works.
