摘要
以地震破裂带,极震区长轴及发震断裂等为基础资料,统计了中国西部的强震构造。结果表明,其走向和长度均服从正态分布,并存在线性相关关系。为此,建立了构造走向与长度之间的回归方程。分析了破裂带与地震构造类型、发霉构造与区域应力场之间的关系,讨论了北西向发震构造在中国西部占主导地位的原因。
Based on the investigation of seismic rupture zone, long axis meizoseismal region and seismo generating fault, we make the statistic analysis of the strong seismotectonics in west of China. The results show that both the length and strike of seismotectonics are in accord with normal distribution, and the relationship between them is linear. Then, the regression equation has been set up. The relationship between the rupture zone and seismotectonic type, as well as the relationship between the regional stress field and the seismogenic structures have been analysed. Finally, the reason why NW seismogenic structures in west of China are in dominant position has been discussed also.
