Abstract
Many countries around the world have accelerated the paces of space exploration in recent years. The small gravity field on the surface of the Lunar, Mars and other stars has shown its great influence on the mechanical properties of subsurface soils. A type of magnetic cohesionless soil, made from the cement and Fe3O4 magnetic powder, was prepared and adopted to carry out a series of triaxial compression tests under a confining stress condition within the range of 5-30 kPa. The tests were conduct under four different gravity fields (i.e. 0 g, 1/3 g, 2/3 g and 1 g; g indicates the earth gravity acceleration), by using the geotechnical magneto-gravity model testing equipment developed by China University of Mining and Technology. The experimental results show that the mechanical properties of cohesionless soil, including tangential modulus, failure strength, cohesion and friction angle, tend to increase with the gravity field during the shearing process, when a constant confining pressure is applied. In addition, relationships between the mechanical properties and gravity field were proposed. This research provides some insights into the mechanics under various gravity-induced stress gradients, and therefore contribute to the further development of surface excavation, base construction and resource exploitation on the Lunar, Mars and other planets.
