Back analysis of rheological deformation characteristics of Gongboxia Concrete-Faced Rockfill Dam
摘要
Abstract
In order to study the rheology of rockfills and its influence on the stress and deformation of the concrete face, the monitoring deformation data of the Gongboxia Concrete-Faced Rockfill Dam was analyzed. The viscoelastic rheological model Merchant was applied to determine the relevant rheological parameters of the rockfills by back analysis. The stress and deformation of the dam during the operation were calculated using the obtained rheological parameters. The results show that the rheology of rockfills is relatively obvious and the computed results agree well with the measured values. The rheology of rockfills has great impact on the stress and deformation of concrete faces, vertical joints and peripheral joints. The rheological model and parameters obtained by back analysis are reasonable, and can be used to predict the development of axial stress and the cracks occurring trend in the concrete face.关键词
