【摘要】 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更多还原

【Abstract】 According to the information about the barriers and earthquake ruptures in the strike-slip active fault zone of China’s mainland,we discussed their relations and segmentation significance between the barriers yardsticks and the earthquake ruptures.The result is that the magnitude of earthquake occurred in the strike-slip active fault and step distance of the barriers have linear relations,so do the step distance and the secondary segment length. S=3*M-21.75;L=23 93*S -1 25,So, we think that the step distance is an important scale to judge the yarstick at which earthquake rupture stop, and is the sign and foundation of active fault rupture segmentation.更多还原
