Abstract


The dam is the sloping core rock-fill dam. In the process of construction and store water, the sloping core of dam and high-ductility clay go through the change procession of the unsaturation and consolidation saturation. To ensure the safety of the dam and provide the technology for the decision during the process of construction and store water. In this article, the elastic-plastic stress-deformation of dam is calculated and the consolidation is analyzed. Including the rock-fill dam, the stress and deformation distribution of cut-off wall, the deformation of sloping core, the incresment and subduction of pore water pressure and the effective stress situation calculation. In the calculation, the experiment parameters are adjusted through the feedback analysis and how to choose the material parameters are investigated. At last, based on the feedback analysis of the data of site investigation, the suggestions about whether to supply drainage measures in the catchment of high-ductility soil area are provided.
