对冻盐粉质粘土进行了一系列单轴抗压强度试验。试验结果表明：在试验范围内，抗压强度随含盐量的增加和试验负温度的降低呈线性降低；在一定应变速率下，屈服强度与抗压强度随温度和矿化度的变化密切相关。提出了相对温度的概念，并给出了不同试验温度和矿化度下相对温度与抗压强度之间的线性关系。相对温度可以将非盐渍土与盐渍土的力学性质联系起来。
A series of uniaxial compressive strength tests were conducted on frozen saline silty clay.The test results show that: within the test range condition,the compressive strength decreases linearly with increasing salt content and descending test negative temperature.For a certain strain rate,the yielding strength is closely related to the compressive strength with the variation of temperature and salinity.The concept of relative temperature is proposed,and a linear relationship between the relative temperature and the compressive strength at different test temperature and salinity is presented.The relative temperature can be used to link the mechanical properties of non-saline soil with those of saline soil.
