متن کاملTrench stability in cohesive soil
Trench is connected to very narrow and deep excavation filled with bentonite suspension. This paper presents estimation of its stability in cohesive soil. The stability is assessed by two calculation methods. The first involves the equilibrium of forces acting on the rigid wedge. The second one includes numerical calculations conducted in Plaxis 3D Foundations. A few examples having different d...

متن کاملDynamically Supported Trench Topography
A viscous flow model of a subduction zone is used to calculate the near-trench deformation and topography of the overriding plate in response to tectonic and buoyancy forces. The tectonic force, which is associated with global plate motion, arises from subduction of a cold oceanic lithosphere that shears the overriding lithosphere along the contact between the two plates. The buoyancy force ari...
