前言地震土-结构相互作用(SSI)分析已成为核电厂抗震设计中不确定性的来源之一。过去15年中已开发了一系列SSI分析技术和有关的计算机程序。虽然理论和分析方法日益改进,但不同的方法常得出显著不同的反应预测结果。由于缺少计算方法的论证,因此往往只能采用包络各种方法分析结果的保守做法,这种做法虽然有其保守的一面,但并未减小其不确定性,因此也不一定就提高了结果的可靠性。为了验证几种在美国核工业领域里常用的SSSI分析方法,美国电力研究所(EPRI)与台湾电力公司(TPC)合作在台
Introduction Seismic soil-structure interaction (SSI) analysis has become one of the sources of uncertainty in the seismic design of nuclear power plants. A series of SSI analysis techniques and related computer programs have been developed over the past 15 years. Although theory and analytical methods are improving, different methods often result in significantly different reaction predictions. Due to the lack of demonstration of calculation methods, conservative approaches that often use enveloped methods to analyze the results are often used. Although this approach has its conservative side, it does not reduce its uncertainty and therefore does not necessarily increase the The reliability of the result. In order to verify several SSSI analysis methods commonly used in the US nuclear industry, the American Electric Power Research Institute (EPRI) cooperates with Taiwan Power Company (TPC) in Taiwan.
