| 摘 要： | 本文以自行研制的粘土矿物钝化剂对广东省和武汉市等六地区的土壤进行了钝化改性实验研究，并对钝化效果的影响因素做了初步的分析探讨。实验表明，虽然6个地区11个样品中的粘土矿物种类和含量不同，但钝化剂对所有样品都有稳定的作用。其稳定效果，不仅与样品的物相组成和粒度分布有关；而且还与粘土矿物的种类及其含量密切相关。就三种主要粘土矿物来说，钝化效果的顺序是高岭土＞伊利石＞蒙脱石。

| Abstract: | The experiment on the passivation effects has been done of 11 soil samples from different places in Guangdong Province and Wuhan City by using passivant developed by ourselves. The result shows: the passivant causes an increase in mechanical strength and a decrease in expansion quantity of all soil samples to raise the soil stability and the passivation effect is related to chemical composition and particle-size distribution, but also the type and contents of clay minerals in the soil samples. In the three kinds of clay minerals the effect of kaolinite is better than that of illite and montmorillonite. |
