Abstract Triaxial compression tests were conducted on frozen sandy soils under a constant minimum principal stress (σ3 = 1.6 MPa) and various intermediate stresses (σ2 1.6, 3.4, 5.2, 7.0, 8.8, 9.8 MPa). The purpose of the research was to investigate influence (σ2) characteristic levels deformation characteristics. test results obtained demonstrated that crack damage failure initially increase then decrease with an in σ2. However, initiation exhibits initial up specific value, after which it stabilizes. difference between σ2 σ3 directions increased increasing From perspective propagation, mechanism strength is discussed. revealed using superposition principle Poisson’s effect. Finally, constitutive model based Weibull distribution Drucker-Prager criterion can accurately represent stress-strain relationships conditions.

The presence of frozen clay as a natural protective material makes it crucial layer defense against potential impacts in various engineering projects. Studying the strength and deformation characteristics is, therefore, particularly important. In this study, static mechanical tests, Hopkinson impact test, fly-plate tests were conducted on to identify its properties under an load. uniaxial compression strength, flexural elastic modulus displayed linear increase with change temperature. fractal dimension was used describe failure clay, yielding values ranging from 1.5691 1.8785. At same temperature, exhibited strain rate effect increased. A light gas gun system then conduct at varying temperatures (−3, −20 °C, ordinary temperature). process meticulously analyzed, considering factors such shock wave velocity, particle velocity behind wave, pressure, volume strain. Moreover, our investigation plotted D–u (volume strain–particle velocity) P–μ (impact pressure–shock adiabatic curves. Notably, we observed that samples higher initial increased resistance identical density moisture content, resulting discernible leftward shift curve. results provide theoretical basis technical support for similar projects future.
