Abstract

This article summarises a laboratory program involving over 100 tests that were performed to study the influence of soil type, temperature, water content and salinity on the strength and creep of frozen soils under uniaxial compression and shear tests. Analyses of experimental data allowed to get equations for predicting strength and creep parameters depending on the temperature and salinity using generalising parameters for frozen soils (freezing point and the concentration of pore solution). These parameters reflect the total impact of all factors (soil type, salinity and water content) in forming a single pattern for all types of soil. The developed theory of searching for generalised dependencies showed a good convergence for predicting the strength and creep characteristics of frozen soils.

摘要

本文总结了一项涉及 100 多项试验的实验室计划，这些试验旨在研究土壤类型、温度、含水量和盐度对冻土在单轴压缩和剪切试验下的强度和蠕变的影响。对实验数据的分析允许使用冻土的通用参数（凝固点和孔隙溶液的浓度）获得预测强度和蠕变参数的方程，具体取决于温度和盐度。这些参数反映了所有因素（土壤类型、盐度和含水量）对所有类型土壤形成单一模式的总体影响。发展起来的寻找广义依赖关系的理论在预测冻土的强度和蠕变特性方面表现出良好的收敛性。
