Abstract: By indoor experiments the dry shrinkage and temperature shrinkage characteristic of powdered soil are systemically researched. And it shows the shrinkage index of powdered soil stabilized by lime and solidification CLG powder are bigger than that by cement and solidification SS-108. Futhermore,the shrinkage index of powdered soil stabilized by binder and solidification increase with more binder

Key words: dry-shrinkage, temperature-shrinkage, dry-shrinkage index, temperature-shrinkage index

摘要： 通过室内试验对水泥稳定粉土、石灰稳定粉土及固化剂稳定粉土干燥收缩和温度收缩性能进行系统研究，得 出无机结合料和固化剂稳定粉土干缩系数和温缩系数变化规律，结果表明石灰及石灰基CLG固化剂稳定粉土收缩 系数大于水泥及水泥基SS一108固化剂稳定粉土，而且随结合料剂量增加，无机结合料和固化剂稳定粉土干缩和温 缩系数增大
