前言在过去十年中,石油工业已承担了全世界有地震危险的海域内开发海洋石油与天然气贮藏的任务。随着先进技术的发展,这种活动已成为海洋平台抗震分析与抗震设计的主要推动力。一个海洋平台的选址,很少是由地震 Foreword Over the past decade, the petroleum industry has assumed the task of developing offshore oil and natural gas storage in sea areas that are at risk of earthquakes around the world. With the development of advanced technologies, this activity has become the main driving force for seismic analysis and seismic design of offshore platforms. The location of an ocean platform is rarely caused by earthquakes
