The influence of membranes on tests of coarse-grained materials at low cell pressures
, 2014 In triaxial tests on small specimens of sands/silts and clays, cell pressures are usually greater than 100 kPa and membranes are relatively thin (~0.3 mm).

Knowledge Extraction via Machine Learning Guides a Topology‐Based Permeability Prediction Model
Water Resources Research, Volume 60, Issue 7, July 2024.Abstract The complexity and heterogeneity of pore structure present significant challenges in accurate permeability estimation. Commonly used empirical formulas neglect its microscopic and topological characteristics, thus lacking accuracy and adaptability. While machine learning (ML) and deep learning (DL) models demonstrate promising performance, but

Probability Analysis Method of Seismic Response for Earth-Rockfill Dams
AbstractSeismic response probabilistic analysis for earth-rock dams is a crucial step in performance-based seismic safety evaluation. It represents a significant transition from deterministic analysis to stochastic analysis. To conduct such an analysis, it's essential to thoroughly consider the uncertainties associated with the seismic response of ...

Deformation and cracking in rockfill dams : case of Jatiluhur dam
, 2004 Rockfill dams are embankment type of dams whose stability primarily depends onrock properties. The term rockfill dam usually represents a dam that contains morey of its foundations and the occurrence of cracks mayause serious problems in embankment dams.

Dynamic probability evaluation of safety levels of earth-rockfill dams using Bayesian approach
Water Science and Engineering, 2009 AbstractIn order to accurately predict and control the aging process of dams, new information should be collected continuously to renew the quantitative evaluation of dam safety levels. Owing to the complex structural characteristics of dams, it is quite difficult to predict the time-varying factors affecting their safety levels.

Rockfill dams – downstream riprap and dam toe : FoU-project 80409 [PDF]
, 2021 The Norwegian regulations for dam safety and the guidelines on embankment dams include requirements for erosion protection of upstream and downstream slopes of embankment dams. Two recent PhD-studies at NTNU have focused on riprap design on rockfill dams
