Particle mechanics modeling of creep behavior of rockfill materials under dry and wet conditions
Keywords: Rockfill creep Particle mechanics method Water weakening Wetting–drying cycles Particle breakage Abrasion a b s t r a c t Rockfill is an important construction material for infrastructure engineering, such as dams, railways and airport foundations, which display a long-term post-construction settlement. However, the main mechanisms for rockfill creep and weathering influence still rem...
متن کاملmortality forecasting based on lee-carter model
over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...
15 صفحه اولEvaluation of Grading Effect on Behavior of Rockfill Materials via Large-Scale Experiments
The rockfill structures are widely constructed throughout the world and rockfills are largely used in these structures as main materials or filler materials. In the crust of earth dams, the rockfill materials role is to stabilize the body of the dam, however, the behavior of these materials in Particular their shear strength is not fully understood. In this study, different tests have been cond...
متن کاملbehavior of rockfill materials in triaxial compression testing
this paper studies thoroughly and deeply the results of about one hundred triaxial compression tests on thirty types of rockfill materials. the materials are categorized in accordance with their particles shape (angular / rounded) and gradation characteristics. the main tool of the study is the hyperbolic model developed by duncan and chang. the focus of the study is on the variations of deform...
متن کاملNumerical Simulation on Slabs Dislocation of Zipingpu Concrete Faced Rockfill Dam during the Wenchuan Earthquake Based on a Generalized Plasticity Model
After the Wenchuan earthquake in 2008, the Zipingpu concrete faced rockfill dam (CFRD) was found slabs dislocation between different stages slabs and the maximum value reached 17 cm. This is a new damage pattern and did not occur in previous seismic damage investigation. Slabs dislocation will affect the seepage control system of the CFRD gravely and even the safety of the dam. Therefore, inves...
