The widely used wet‐screening method in the experimental testing of hydraulic fully graded concrete inevitably results a gap between real mechanical parameters specimens and those corresponding wet‐screened therefore necessitates comparative study on their behaviors. To this end, two‐dimensional mesoscale modeling methodology is developed for simulating tensile fracturing behaviors concretes, extensive Monte Carlo simulations are performed. individual effects specimen size variation,...
The cracking behavior and failure mode of a 78 m high concrete double‐curvature arch dam with weak upper abutment are investigated through performing analysis. mechanical is simulated using smeared crack model, in which combination the compression yield surface detection damaged elasticity concept employed to describe concrete. practical properties lower abutments firstly studied emphasis on its during overloading. Then, comprehensive sensitivity analysis carried out investigate influence...
In this paper, the failure process of concrete arch dam is focus research. Based on quasi-static solution technique, explicit analysis method used to study 78m high double-curve under condition homogeneous foundation. The whole plastic with foundation in overload from local damage studied. numerical simulation results show that same load case, calculation and implicit are basically same. does not converge when overloaded factor 1.64, based technique can simulate more complete. When reaches...
