... judged to be conservative (safe for design) based on comparison with measured loads for both walls. Reinforcement loads were observed to increase with decreasing toe support, particularly at the base of the walls. A fully developed composite soil failure mechanism propagating from the heel...

...Natalia Melnikova, PhD; David Jordan, MSc, CEng, MICE; Valeria Krzhizhanovskaya, PhD; Peter Sloot, PhD The paper analyses the experimental slope failure of a full-scale earthen dyke (levee) in Booneschans (Groningen, the Netherlands). The goals of the experiment were to develop efficient dyke...

.... Therefore the assumed failure surface, from which s_u-FV is calculated, is quite different from the actual failure surface. In fibrous peat, fibres often wrap around the vane during rotation and increase the resistance being measured. Figure 1 shows an example of a typical variation...

... reasonable factors of safety, φ′ is determined at strains far below failure, and the true strength of the material is not accounted for. For a realistic assessment it is necessary to combine (low) stiffness and (high) strength parameters in one analysis, and the finite-element method is the obvious...

... together factors affecting different failure modes, may be misleading. The methodology presented in this paper, developed to overcome these limitations, is based on the estimate of the probability of breaching associated with a limited range of water levels. In this work, while other failure modes...

...Abouzar Sadrekarimi, PhD The 1971 San Fernando earthquake led to the failure and large displacement of the Lower San Fernando dam, which was constructed by the hydraulic filling method. Hydraulic filling has been condemned as producing liquefiable sand deposits, and in situ relative densities...
