Study on Optimization of High Concrete Face Rockfill Dam Filling Procedure
In this paper, the influence of concrete faced rockfill dam (CFRD) filling procedure parameters, such as staged-filling height difference, super filling height, dam settlement in advance, etc.on deformation of concrete slab is studied by adopted Clough-Duncan interface model.The result shows the degree of separation between concrete slab and cushion layer has obvious difference with different filling procedure, and the optimization of dam staged-filling construction scheme is the effective measure to reduce and avoid the separation.Combining with CFRD filling procedure optimization research, particle swarm optimization model for high CFRD staged-filling design is set up.The heterogeneous particle swarm optimization algorithm is adopted to staged-filling plan construction optimization calculate for deformation control of high CFRD concrete slab.
