本文以充分的实验结果为依据，讨论了加载率对岩石材料的强度、断裂韧度和破碎效果的影响。结果表明，在静态或准静态加载条件下，一般岩石的强度的断裂韧度随加载率的增加稍有增加，但当加载率超过一定值（如一般的冲击加载）后，它们随加载率的增加而显著提高。同时，单个岩块和岩石料层在冲击破碎时的能量利用率只是静压破碎时的一部分，即静载更有利于岩石破碎。
Based on the sufficient experimental results, the influence of loading rate on the strength, fracture toughness and breaking effect of rock materials is discussed in this paper. The results show that under static or quasi-static loading conditions, the fracture toughness of general rock strength increases slightly with the increase of loading rate. However, when the loading rate exceeds a certain value (such as ordinary impact loading), their fracture toughness increases with loading rate Increase significantly increased. At the same time, the energy utilization of single rock mass and rock mass during impact crushing is only a part of static crushing, that is, static loading is more conducive to rock crushing.
