Coupled surface-internal deformation monitoring in three-dimensional space for freezing-thawing soil
Publikováno v:
Soils and Foundations, Vol 64, Iss 3, Pp 101468- (2024)
Soil frost deformation significantly influences engineering projects in cold regions. The anisotropic behavior of soil, involving surface and internal deformation in three dimensions (3D), introduces inaccuracies in evaluating freeze–thaw geologica
