【摘要】 膨胀土是一种特殊的粘性土,具有遇水膨胀、软化,失水收缩、硬化等工程特征,掺入水泥或石灰后其工程特性会发生改良。选取南阳中等膨胀土,进行水泥与石灰改性研究。通过改性土的基本物理力学性质试验,对比研究了水泥与石灰改性的效果,为膨胀土渠道、边坡等设计施工处理提供科学和有价值的依据。更多还原

【Abstract】 This paper presents the results of soil improvement for expansive soil using cement-stabilization and lime-stabilization.The effect of soil improvement on a medium expansive soil from Nanyang is demonstrated by comparing the shear strength before and after the treatment.This soil improvement method will have wide application to ditches and slopes constructed with modified expansive soil.更多还原
