| Abstract: | Calcareous sand is a kind of easily crushed granular materials. Based on analyzing the mechanism of grain breakage, the authors establishe a crushing energy equation coupling crushing with dilation. It is proved that the relationship bet ween B r and 1, W p and W B is confirmed by the experiments, and bence the evaluation index and energy equation for calcareous sand crushing are set. |
