A STUDY ON THE RELATIONSHIP BETWEEN SMECTITE CONTENT AND SWELL POTENTIAL INDICES

  • 摘要: 对沿南水北调中线工程邯郸永年、南阳、平顶山等地区及襄樊、荆门钟祥地区采集的各类地表、近地表膨胀土样品5 6件 ,运用现代XRD定量方法和有机染料吸附方法测量了粘土矿物成分和蒙皂石含量 ,同时测定了它们的液限、塑限、自由膨胀率、比表面积、粘粒、胶粒含量等指标。蒙皂石含量与各种膨胀势判别指标研究表明 ,蒙皂石含量是各种膨胀势的主要控制因素。当然 ,各种测量误差 (主要是蒙皂石含量的测量误差 )也是影响膨胀势判别的因素。Seed膨胀势较本文采用的推荐方案划分结果高 1~ 2个级次。蒙皂石含量与各参量之间呈线性、对数、指数关系 ,与粘土矿物的诊断吸收特性一起 ,这为膨胀土遥感提供了基础.
