Vibratory roller compaction is a well-known method in improving the mechanical properties of field rockfills. However, meso mechanism rockfill densification under vibratory has not been understood clearly. This paper presents discrete numerical to simulate Firstly, particles were modeled by irregular and stochastic clusters, which can be breakable. In addition, segregation rockfills was replica...

To address the uncertainty problem in assessment of overall safety trend dams and selection warning indicators, an Extended Cloud Model (ECM) combined with Analytic Hierarchy Process (EAHP) method is proposed this study. In new approach, different factors reflecting dam monitoring have been considered as a fuzzy system. Considering characteristics forward cloud model backward model, original da...

Inversion analysis is usually an efficient solution to process the monitoring data of earth-rockfill dams. However, it still difficult obtain calculation results that are consistent with due different construction statuses. To deal this situation and introduce a new improve accuracy, general method inversion based on back-propagation neural networks original step-by-step assuming parameters con...
