Research on the design and analysis method of ice landscape structure considering the temperature effect

This paper proposes a design and analysis method for ice landscape structures that accounts for temperature effects. First, uniaxial compression tests and split-tension tests were conducted under various low-temperature conditions to systematically investigate the fundamental mechanical behavior of natural pure ice. Second, addressing the material’s pronounced temperature sensitivity, a thermoelastic constitutive model incorporating temperature effects was developed, along with a thermal-force coupling analysis method considering non-uniform temperature fields. Finally, continuous response monitoring was implemented based on practical ice structure engineering applications. The results demonstrate that ice exhibits significant brittleness and tensile-compressive anisotropy, with its compressive strength, tensile strength, and elastic modulus all increasing linearly with decreasing temperature. The surface snow layer of ice structures provides substantial thermal insulation, effectively slowing their melting rate. This study elucidates how localized non-uniform solar radiation influences ice structure deformation and thickness, providing crucial theoretical foundations and engineering support for structural design, numerical simulation, and safety assessment.
