Dan Hu · Water Resources and Power · 2013
Based on the extenics theory of matter-element model,assessment method of dam slope stability is proposed in this paper.The classical domain and joint domain of matter element are determined by constructing the element dependent function and dependent degree.And the assessed model of dam slope stability based extenics theory is established.Then the multiplication scale method is adopted to calculate weight and assess and predict the dam slope stability quantitatively.The proposed evaluation model is applied to practical project.Compared with 2D finite element method,the results show that two methods are identical.Therefore,the extenics method is feasible for assessing dam slope stability.It is simple and convenient practical by comparing with the traditional method,which can apply in similar assessment and prediction of dam slope stability.
