Using three-point bending beam test,analyse the Influence of water-cement ratio and coarse aggregate particle size to fracture behavior of dam concrete.The results show that the load-deflection curve of dam concrete is divided into add segments quickly,descent segments quickly and descent segments slowly;when water-cement ratio and coarse aggregate particle size of dam concrete are 0.4 and 30mm,minimum brittleness.The research results can provide reference for optimal design of gradation of dam concrete.
