This article focuses on peat soil ofthe region of the Dian Chi Lake inKunming, the peat soil as research subject. This paperstudy on unconfined compressive strength test of solidifiedpeat soil mainly. In the experimental study of chemical admixtures curing peatsoil, the test hadeight groups. The experimental study of cement soil of different kindsof additives, and study the impact of additives on curing peat soil. It was concluded that the regularof cement soil compressive strength with the increases of chemical admixtureand curing time.
