【摘要】 通过对原状土和冻融土的物理、力学性能的试验研究 ,得知土冻结融化后其物理、力学性能发生了很大的改变 :孔隙比、压缩系数、渗透性明显增大 ,单轴和三轴抗剪强度等明显降低。并对这些变化进行了比较分析 ,以探讨冻融土的沉降机理及治理方法更多还原

【Abstract】 Though experimental studies of the physical and mechanical properties of soil and freezing thawed soil respectively,conclusion was drawn with regard to the changes of physical and mechanical properties of the freezing thawed soil.Apparent increases were witnessed in porosity ratio,compression coefficient and permeability with decreases in uni axial and tri axial shearing resistance.Simultaneously,comparative analyses were conducted into the settlement mechanisms and treatments of the treezing thawed soil.更多还原
