序言最近非常重视地震荷载参数的概率评价方法,尤其是用概率方法预报等震线图和等加速度线图。一旦定义了震源释放、传播方式及场地效应以后,就可以用任何地面运动参数制定危害性图。典型的作图程序包括三部分:·震源的地震活动性模型 Preamble Recently, great attention has been paid to the method of probability evaluation of seismic load parameters. In particular, the isokinetic method is used to predict isoseismic maps and iso-acceleration maps. Once the source release, mode of transmission, and site effects have been defined, hazard maps can be developed using any ground motion parameters. A typical mapping program consists of three parts: • Seismicity model of the source
