中文摘要：

以水泥土在季节性冻土地区的路基、基坑挡土墙以及堤防防渗墙等水泥土工程中的安全性为研究背景，对不同冻融循环次数后的水泥土进行抗剪强度、抗压强度以及渗透系数试验，得到了不同冻融循环次数对水泥土抗剪强度、抗压强度以及渗透系数影响的试验数据．试验数据表明，水泥土的抗剪强度、抗压强度随着冻融循环次数的增加而降低，水泥土的渗透系数随着冻融循环次数的增加而增大，建立了水泥土抗剪强度、抗压强度以及渗透系数随冻融循环次数变化的回归曲线方程．结果表明水泥土在季节性冻土地区应用时应考虑冻融循环对水泥土力学性能的侵蚀效应．

英文摘要：

The safety analysis of cemented soil is foundation in the seasonal frozen regions, impermeable walls. Original laboratory tests essential in the cemented soil retaining wall in foundation were performed on cemented treatment of different times of freezing-thawing cycle. The influences of engineering, e. g. road pits and embankment soil samples after the freezing-thawing cycle time on the shear strength, compressive strength and permeability of cemented soil were analyzed. The experimental results showed the shear strength and compressive strength decreasd with the increase of freezing-thawing cycle time opposite trend. And the relationships between strength , while the evolution of permeability showed the the freezing-thawing cycle time and the shear , compressive strength and permeability were established by the fitting method. The experimental results also showed that the freezing-thawing cycle had a significant influence on the shear strength, compressive strength and permeability of cemented soil, and this influence should be taken into account for the application of cemented soil in the seasonal frozen regions.
