摘　　要：建立了一种适合动载荷条件下岩石破坏模拟研究的实验装置,并通过实验研究总结出了一定实验条件下的动载特征与岩石开裂裂纹数量的定量经验关系式,同时分析了岩石破坏形成多裂纹的条件及主要影响因素,对低渗油气藏开发中油层改造施工作业具有一定的指导意义。The paper describes the experimental ap- paratus established for simulating rock dynamic fracturing under a certain dynamic loading condi- tions, summarizes the quantified empirical formula concerning dynamic loading characters and num- bers of cracks formed under a certain experimental conditions, and also analyzes the conditions and key factors for multi-fractures formed by rock dy- namic fracturing, which has great significance in formation treatment operation for low-permeability reservoirs.
