摘　　要：研究岩石和被冲击物体的弹性模量对冲击力的影响,对于滚石灾害的防治研究具有重要意义。在室内进行试验设计模拟岩石冲击的过程,选取不同岩石和被冲击物体的弹性模量作为影响因素,获得了弹性模量与冲击力之间的关系。结果表明:岩石和被冲击物体的弹性模量与冲击力之间都成正比关系,岩石弹性模量对冲击力的影响效果要强于被冲击物体弹性模量对冲击力的影响,但差距不大。根据试验结果,拟合出被冲击物体弹性模量、岩石弹性模量和冲击力三者间的关系公式。The study of the influence of elastic modulus of rock and impacted object on impact force is of great significance for the prevention and control of rolling stone hazards.In the laboratory,the process of rock impact was simulated,and the elastic modulus of different rocks and impacted objects were selected as influencing factors to obtain the relationship between the elastic modulus and impact force.The results show that the elastic modulus of the rock and the impacted object is proportional to the impact force,and the effect of the elastic modulus of the rock on the impact force is stronger than that of the elastic modulus of the impacted object,but the difference is not large.According to the test results,the relation formulas of the elastic modulus of the impacted object,the elastic modulus of the rock and the impact force are fitted.
