Recently, the efficient use of cold energy, a type of natural energy derived from snow and ice, has been studied as an energy-saving measure to cut emissions of carbon dioxide. For example, the Ice Shelter, which is constructed with natural ice, was developed to create an environment with low...
The purpose of this study is to investigate the settlement of the embankment constructed in warm and ice-rich permafrost (WIRP) region along the Qinghai–Tibetan Railway (QTR). In this investigation, an in-situ experiment for the thermal regime under this embankment and for the settlement of the...
An extended model of the ice–structure-interaction process in ice-induced vibrations has been derived from the Matlock-model. The model has been applied to full-scale simulations, including variations of ice and structure parameters. It turns out that some generalised assumptions – usually...
This paper presents results of two experiments on snow stress measurements under vehicles running over snow pack. In the experiments, a 5.6 T 4 × 4 military truck and a grooming machine were used. The military truck was driven over a 30-cm shallow snow pack in which a stress state transducer...
A series of triaxial compressive tests of frozen soil has been conducted at a temperature of − 6 °C under high confining pressures. The results verify that the strength of frozen soil increases to a peak value with increasing confining pressure, but with a further increase in confining...
The objective of this study was to investigate the strength characteristics of frozen rubber–sand mixtures. Uniaxial compressive strength, direct-tensile strength and direct-shear tests were conducted on rubber–sand mixtures at various rubber contents (0, 10, 15, 20, and 30%) and low...
Operations in ice-covered waters require good engineering to ensure the safety of personnel and the environment. In polar regions, the presence of sea ice is the main factor hindering the operations. It affects shipping, and oil and gas exploration and development. This paper looks at the stage...
