摘要
本文引进了广义的水平位移概念,并据此提出地震地表破裂带一(微)段上的位移量取方法,即用次级破裂端部推挤区或拉分区内的构造水平位移近似代替两侧次级破裂上的水平位移;破裂带上一(微)段的水平位移等于通过该点垂直于破裂带走向方向上的数条破裂的位移之和。
A conception of displacement in wide sense is introduced in this paper. According to the conception, the methods of measuring displacement on the surface rupture of earthquake are presented, which are (a)taking displacement in pushing up or pull-apart area in fracture terminal approximately as the displacement on the bilateral secondary shear-fractures,and(b)the displacement at one point through which there are several fractures in the direction perpendicular to the surface rupture zone is the sum of the displacements on the several fractures.
