Application of Gudehus-Bauer hypoplastic model of core-wall type rockfill dams considering wetting behavior
摘要
Abstract
Based on the analysis of main characters of weathered rockfill materials, the deformation of rockfill due to a change of the moisture contents can be forecasted using an extended Gudehus-Bauer hypoplastic model. The updated model takes into account a moisture sensitive granular hardness; and it can reflect the influence of density, stress state, rate of deformation and moisture content on the nonlinear, inelastic stress strain behavior of rockfills. Numerical simulation is carried out to simulate the evolution of deformation and stress of a core-wall type rockfill dam during the first water impounding. The results are reasonable.关键词
