| 摘 要： | 在国家和地区地震动区划和重大工程的地震安全性评价工作中，区域地震动衰减规律的确定是重要环节，而借用法是目前常用的建立区域地震动衰减的方法。我国借用法通常都把美国西部作为参考地区，但一般都采用调整美国学者已有烈度衰减规律的办法确定美国西部烈度衰减规律。本文讨论美国西部已有烈度衰减规律，并直接采用美国西部烈度调查资料建立烈度衰减规律，结果可供我国工程地震工作者参考。

| Abstract: | Determination of ground motion attenuation laws is an important link in the national and local seismic zonation and the seismic safety evaluation of key projects. The borrowing method is generally used to establish the earthquake ground motion attenuation law of a rejion. This method usually selects the west of US as the reference region in China,but the intensity attenuation laws in the west of US is generally determined by adjusting the known intensity attenuation laws given by the american scholar. This paper discusses the known intensity attenuation laws in the west of U.S.,and directly makes use of the intensity investigation data to establish the intensity attenuation laws in the west of U.S.,the results may supply references to earthquake engineers in our country. |
