The deformation patterns and failure mechanisms of pressurised cavities at shallow depth are relevant to many geotechnical applications, including tunnelling horizontal directional drilling. In this paper, an experimental study a reduced-scale cavity under geostatic stress is presented, in order measure the effect length, vertical soil density on failure. X-ray computed tomography used acquire ...

Squamates classified as 'subarenaceous' possess the ability to move long distances within dry sand; body elongation among sand and soil burrowers has been hypothesized to enhance subsurface performance. Using X-ray imaging, we performed the first kinematic investigation of the subsurface locomotion of the long, slender shovel-nosed snake (Chionactis occipitalis) and compared its biomechanics wi...

Geosynthetics (GSN) are polymeric products used in Geotechnical Engineering for the purpose of improving properties insitu soil. In this project, experimental work was carried out to determine influence presence fines within granular soil on CBR strength reinforced with different GSN (Woven geotextile, Non-woven Geogrid and Geonet). Two types disturbed state containing varying percentage were s...

The procedure of granular column installation impacts soil properties such as stress state, stiffness, and permeability in the near-field column. For an accurate efficient design relatively costly geostructures on improved subsoil with columns, a reliable estimation effects natural deposits is necessary. To achieve this goal, two phases are adopted numerical simulations: (1) phase based cavity ...
