摘要
膨胀土的分布范围很广,其吸水膨胀,失水收缩的特性给工程的施工和工程结构的安全性带来了很大的隐患。采用水泥改性安阳地区中膨胀土,在增加改性土强度的同时,又改变了其膨胀性能。通过多种试验方法,从宏观力学特性,微观结构特征等方面对水泥改性中膨胀土进行了一定的研究,揭示了水泥改性中膨胀土的内在机理。
Expansive clay , which has a widespread distribu neering construction and the safety of engineering structures due tion, has brought great hidden trouble to the engi- to their swelling and shrink properties when mois- ture content changed. Adopting cement to treat expansive clay in anyang region can change its swell and increase its strength. Adopting many different testing methods, cement treated Anyang clay was investigated from macro me- chanical behavior and microstructure characteristics, which reveal the inner mechanism.
