3D effects of soil-atmosphere interaction on infrastructure slope stability

It has long been established that pore water pressure (pwp) variations affect the stability and serviceability of slopes. Pwp may be due to consolidation/swelling processes within soils low permeability or seasonal evapotranspiration precipitation processes. The simultaneous study such phenomena hydro-mechanical coupling in sloping ground requires use advancednumerical methods. Often, infrastructure slopes are considered plane strain (two-dimensional) conditions for simplicity date this is case most numerical analyses considering soil-atmosphere interaction. However, approach makes it impossible longitudinal extent a possible slip surface forming following vegetation removal. Three-dimensional, fully-coupled acut slope were performed herein effect clearance on explore numerically ways implementing effective management.
