人工冻结的杭州饱和软土的单轴抗压强度特性

Unconfined compressive strength behaviour of frozen Hangzhou saturated soft clay

对人工冻结的杭州典型的饱和软土进行单轴抗压强度试验 ,分析了强度曲线的特征 ,得到冻结的杭州饱和软土强度随冻结温度、应变速率、土样干密度的变化规律。其结论对用冻土壁作为基坑围护的开发应用具有实际意义。

Unconfined compressive strength tests were carried out on frozen soil of typical Hangzhou saturated soft clay. Behavior of the stress-strain curves of the tests was analysed; and variation regularity was found of the strength with temperature, strain rate and dry density of the frozen Hangzhou soft clay. The result is valuable for the development and application of frozen soil walls used for supporting of foundation pits.
