RHEOLOGY OF VISCOPLASTIC LANDSLIDES UNDER NATURAL CONDITIONS AND IN CASE OF PILING STABILIZATION
The authors analyze rheological equations of viscoplastic landslides under natural conditions and in the presence of a sparse row of piles as an anti-slide barrier. Rheology of viscoplastic slides in the presence of buttresses that significantly alter the pattern and speed of their motion has enjoyed little attention of researchers, although it plays an important role in the analysis of stabilization of landslide flows. Elements of tensor calculus are used to analyze the motion of the viscoplastic matter. An exact solution to the problem of gravitational motion alongside an inclined plane was used as the main one. It is proven that the motion pattern of the viscoplastic matter contains rigid zones where the flow velocity is equal to zero. In the event of motion of a layer alongside an inclined surface, the rigid zone moves together with the viscous surface, and the overall velocity of the viscoplastic flow will be determined by the rheology of the viscous surface. This paper provides solutions designated for the identification of rigid zones of cohesive soils, as well as soils that demonstrate internal friction and cohesion. The authors have proven that whenever piles are used, the nucleus of the landslide mass is stabilized.
