双环法测定单一均质土层渗透曲线的变化规律

Analysis of Determination Transformation Law of Permeability Curves of Single Homogeneous Soil Layer with Double-loop Test

介绍了双环法测定岩土渗透性的试验装置及其试验原理,分析了使用双环法测定某一建设项目地基土层岩土渗透性所得的渗透曲线,根据渗透曲线表现出整体变化趋势及速率,得出了该渗透曲线变化阶段可分为变化阶段和稳定阶段两个部分,其对应的入渗过程可分为非饱和土壤入渗与饱和土壤入渗的结论。

Double-loop test in wild geotechnical test data is more accurate. In a construction project, analysis of double-loop test the penetration curve, the infiltration process can be divided into two parts： stages of change and stabilizing phase, the each phase corresponding conditions is infiltration in unsaturated soil and saturated soil.
