Abstract

It is of great significance to get real parameters and real running state of the dam based on back analysis in order to evaluate the dam stability exactly and comprehensively. A back-analysis approach for the parameters of earth-rockfill based the analysis of dam stress, deformation and seepage observation data. After the 3-D back analysis, the real parameters of the dam are determined by simulating the dam construction and operation states with the method proposed. The dam safety is then evaluated in quantitatively according to the proposed criterions.
