系统收集了中国大陆走滑活动断裂带上障碍体 (阶区 )与地震破裂的资料 ,探讨了障碍体止裂尺度与地震破裂的关系及其分段意义。统计分析表明 ,走滑活动断裂带上地震的震级与障碍体的阶距、阶距与次级段长度具有较好的线性关系。障碍体的阶距可以作为判定地震破裂止裂尺度的极重要标志 ,是进行破裂分段的前提和基础
The system collects the data of the obstacles (stratum) and the earthquake rupture in the strike slip zone of the Chinese mainland and discusses the relationship between the crack arrest scale and the earthquake rupture and the meaning of the segmentation. The statistical analysis shows that there is a good linear relationship between the magnitude of the earthquake on the strike slip event and the step length of the obstacle body and the length of the secondary segment. The step height of the obstacle body can be used as a very important symbol to judge the scale of crack initiation and rupture, which is the prerequisite and basis for rupture
