- 論文の詳細を見る
An analytical method due to the hybrid finite element formulation is presented for the multi-dimensional elasto-plastic consolidation analysis. To facilitate a reliable consolidation analysis of K_0-consolidated clay layer, an elasto-plastic analytical model is also proposed, which has a yield function with no singularity satisfying the K_0-strain condition on the K_0-line, followed by showing its reasonableness and advantage in numerical computations.To deal with a more realistic consolidation analysis, the presented method is also characterized by the ability to analyze such cases that the drainage is permitted during incremental loading and that the permeability suddenly changes in the layer.Multi-dimensional elasto-plastic consolidation analysis is carried out for partially loaded ground models. The resulting deformation and stress path behaviors substantiate the validity of the presented analytical technique, which brings out some behaviors reflecting the real mechanism of consolidation of clay.
