Different from natural soils, the damage of cementation should be considered in the strength mechanics of lightweight bead-treated soil.
与一般的土体不同的是，其抗剪强度机理应考虑轻质混合土试样胶结结构的逐渐破损效应。

Based on the consideration of fictitious crack and the cementation force of ice in the frozen soil, the two dimensions model of frozen soil roadbed stability are proposed.
Therefore, the present paper has thrown some light on the relation between the macroscopic mechanical properties of soil and its microscopic cementation features.
