在−6 °C温度下,对四种硫酸钠含量(0.0%、0.5%、1.5%和2.5%)的冻结粉质砂进行了三轴压缩试验。试验结果表明,在研究含盐量对粉质砂土强度和变形特性的影响时,首先要确定粉质砂土中硫酸钠溶液的浓度是否饱和。如果硫酸钠溶液浓度和粉砂中硫酸钠含量之一为已知量,则建立了硫酸钠溶液浓度和粉砂中硫酸钠含量相互转换的函数。根据该函数可以方便地判别冻结粉质砂中每一给定硫酸钠含量对应的硫酸钠溶液浓度的饱和或非饱和状态。分析了围压和硫酸钠含量对冻结含盐粉砂的变形特性、破坏模式和强度的影响。
Triaxial compressive tests were conducted on a frozen silty sand with four sodium sulfate contents (0.0%, 0.5%, 1.5%, and 2.5%) at temperature of −6 °C. The test results revealed that it is important and necessary to firstly identify whether the concentration of sodium sulfate solution in the silty sand is saturated for studying effects of the salt content on the strength and deformation characteristics. We established a function which can interconvert the concentration of the sodium sulfate solution and the sodium sulfate content in the silty sand if either one of these two variables is a known quantity. Based on this function, the saturated or unsaturated state of the concentration of sodium sulfate solution corresponding to each given sodium sulfate content in the frozen silty sand can be conveniently identified. The influence of confining pressure and sodium sulfate content on the deformation characteristics, failure mode and strength of the frozen saline silty sand were then analyzed.
