| 摘 要： | 断层运动是复杂多变的, 其运动在一条巨大的断裂带上经常以区段为活动单位, 为服务于工程建设和强震的预测, 划分出活断层运动区段的必要性越来越迫切。本文通过对香山天景山断裂带断层泥的微观特征研究, 结合断裂的几何特征综合分析, 认为该断裂的中段以粘滑活动为主, 东西两段主要是蠕滑。

| Abstract: | Fault movement has a complex and variable pattern and one segment of a great faultzone is usually a unit of rupture. In order to meet the needs for major engineering projects and strong earthquake predication, It is necessary to lacate which segment of a fault zone is active. We propose in this paper that the movement of middle segment of Xiangshan-Tianjingshan fault zone is mainly stick-slip and both its eastern and western segments show mainly stable-slip. On the basis of microstructural characteristics of fault gouge and the segment geometry. |
