| 摘 要： | 通过自制的冻结温度试验装置，以南京地区浅表土为研究对象，分析了淤泥质黏土、淤泥质粉质黏土、粉砂3种不同土质在不同含水率、盐分含量以及不同水质条件下的冻结温度规律。结果表明：在试验的含水率范围内，土体冻结温度随含水率增加呈近似线性升高，随盐分含量增加直线降低，而干密度的变化对土体冻结温度影响不大。

| Abstract: | The shallow top soil in Nanjing was selected as the sample to investigate,the freezing temperature was measured by self-developed equipment.Freezing temperatures of different soils,such as muddy clay,silty clay,mealy sand,at different moisture content,salt content and water quality were analyzed.The results showed that soil freezing temperature enhanced nearly-linearly with moisture content increasing at the equipmental condition.On the other hand,soil freezing temperature decreased sharply with the salt co... |
