Growth of slip surfaces in 3D conical slopes

چکیده
Out-of-plane curvature of real submarine slopes imposes limitations on applicability existing planar criteria for catastrophic growth slip surfaces. In this paper, the an initially weakened zone in three-dimensional (3D) convex and concave is investigated using process approach. The geometry problem presented a curvilinear coordinate system which governing equations surface are derived. Solution these axisymmetric obtained both analytically numerically (using finite differences scheme) benchmarked against Coupled Eulerian-Lagrangian element simulations. It shown that application slope solution to conical constitutes overestimation slope's stability. closed form unstable 3D proposed validated by fitting numerical results various sizes aspect ratios pre-softened zone.

Dynamic growth of slip surfaces in catastrophic landslides.
This work considers a landslide caused by the shear band that emerges along the potential slip (rupture) surface. The material above the band slides downwards, causing the band to grow along the slope. This growth may first be stable (progressive), but eventually becomes dynamic (catastrophic). The landslide body acquires a finite velocity before it separates from the substrata. The correspondi...
متن کامل3D stochastic rock fracture modeling related to strike-slip faults
Fault zones and fault-related fracture systems control the mechanical behaviors and fluid-flow properties of the Earth’s crust. Furthermore, nowadays, modeling is being increasingly used in order to understand the behavior of rock masses, and to determine their characteristics. In this work, fault zones and fracture patterns are reviewed, and also comprehensive studies are carried out on the fr...
