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。
Uniaxial compressive strength tests were carried out on the typical saturated soft soils frozen in Hangzhou. The characteristics of the strength curves were analyzed. The variation of the strength of frozen saturated soft soils in Hangzhou with the freezing temperature, strain rate and soil dry density was obtained. The conclusion is of practical significance for the development and application of the permafrost wall as a foundation pit enclosure.
