NGA计划简介
|
摘要
NGA(Next Generation Attenuation)是一个合作研究计划,由太平洋地震工程研究中心生命线计划(PEER-LL)、美国地质调查所(USGS)、南加州研究中心(SECE)联合实施。该计划旨在通过一个广泛而高度协作的研究计划,研发全新的地震动衰减关系。在整个研发计划中,5套衰减关系由5个互相独立而又互相协作的团队同时研发。该计划的参与者几乎包括了该领域所有美国的顶级专家。希望本文能给我国地震动衰减关系及地震动区划的研究者带来一些启示。
NGA program is a partnered research conducted by Pacific Earthquake Engineering Research Center-Lifelines Program(PEER-LL),U.S.Geological Survey(USGS),and Southern California Earthquake Center(SCEC).It is to develop updated ground motion attenuation relationships by a comprehensive and highly interactive research program.Five sets of updated attenuation relationships are developed by teams working independently but interacting throughout the development process.The developers of the project include nearly all the leading scientists in the field.It is desired that the introduction should be able to inspire the researchers of ground motion attenuation relationship and seismic zonation in China.
