根据大量的冻土单轴压缩试验资料,本文提出可将冻土的应力-应变性状分为9种类型,并分别给出了相应的应力-应变方程。试验结果表明,对一定土质及含水量的冻土,其应力-应变性状主要取决于应变率及温度。根据9种类型应力-应变性状的应变率及温度范围,作者首次提出了冻土单轴压缩本构关系类型图。 According to a large number of uniaxial compression test data of frozen soils, the stress-strain behavior of frozen soils can be divided into nine types, and the corresponding stress-strain equations are given. The experimental results show that the stress-strain behavior of frozen soils with certain soil and moisture content mainly depends on strain rate and temperature. Based on the strain rate and temperature range of the nine types of stress-strain properties, the authors first proposed a uniaxial compression constitutive model for frozen soils.
