Creep parameter inversion for high CFRDs based on improved BP neural network response surface method
The creep parameters of rockfill materials obtained from engineering analogy method or indoor tests often cannot accurately reflect the long-term deformation high Concrete-Faced Rockfill Dams (CFRDs). This paper introduces an optimized inversion based on multi-population genetic algorithm-improved BP neural network and response surface (MPGA-BPNN RSM). used for are determined by parameter sensi...
Concrete-face slabs are the primary anti-permeability structures of concrete-face rockfill dam (CFRD), and resistance face slab concrete to permeability is key factor affecting operation safety CFRDs. Herein, influences five fly ash dosages (namely 10%, 20%, 30%, 40% 50%) on property concretes were investigated. Moreover, difference in caused by dosage variations revealed terms pore structure f...
