| 摘 要： | 本文根据文献1]中有关椭圆形等烈度线的统计结果,讨论了我国东部和西部地区不同震中烈度或震级的地震的平均震源深度和断层破裂长度,提出了适用于点源(以震源距为距离参数)和线源(以场地——破裂线最短距离或场地——破裂线两端点平均距离为距离参数)的烈度衰减规律.

| Abstract: | Based on the statistical outcomes relevant to elliptical isoseisms in ref. 1], the average focal depths and rupture lengths of faults for earthquakes with different magnitudes or epicen-tral intensities that occurred in the eastern and western parts of China are discussed. A set of intensity attenuation functions appropriate to a point sourse (with focal distance as the distance parameter in the attenuation law) and line source (with the nearest distance from site to rupture line or the everage distance from site to both ends of the rupture line as distance parameter) have been proposed. |
