    摘要:

    在对毛毛山断裂带断错微地貌划分对比的基础上详细分析了其位移分布特征。结果表明,毛毛山断裂的水平位移和垂直位移均具较明显的分组现象和可公度性特点。在空间分布上具明显的互补性,从东到西水平位移具累积滑动亏损特征,垂直位移则具累积滑动补偿性,这反映了沿断裂带活动性质与活动强度的差异性和非均匀性。位移累积滑动亏损直接反映了断裂在一定时段内的特征滑动行为,是进行分段的重要依据。

    Abstract:

    In this paper, on the basis of division and comparison of the micro-geomorphy along the Mao-maoshan fault zone, the distribution of displacements is analysed in detail. The results indicate that the distributions of horizontal and vertical displacements along the fault zone have obvious grouping and compensation characters. From east to west of the fault, the horizontal displacements are characterized by cumulative slip deficit, on the contrary, vertical displacements are characterized by compensation. These reflect difference and inhomogeneity of the manners and intensity of faulting. Cumulative slip deficit of displacements directly reflects the behavior of faulting in some period and is an important segmentation scale.
