1.0 序言核电厂的设计常常为核电厂所承受的地震荷载所控制,因而影响了核电厂的造价。因此,确定基本的设计输入地震运动,显然是核电厂设计的一个主要的重要环节。设计用的输入运动广泛地称为安全停堆地震(SSE),在过去这常被称为最大 1.0 Introduction The design of nuclear power plants is often controlled by seismic loads borne by nuclear power plants, thus affecting the cost of nuclear power plants. Therefore, identifying the basic design inputs for seismic motion is clearly a major part of the design of a nuclear power plant. The design input motion is widely referred to as Safe Shutdown Earthquake (SSE), which in the past was often referred to as maximum
