摘　　要：经过30多年的发展,格林已经成为被地震工作者普遍接受的模拟地震动的方法。回顾发展历史,该方法可以分为3个阶段:第1阶段是经验格林函数理论建立阶段;第二阶段是经验格林函数方法逐步得到完善阶段;第三个阶段是经验格林函数方法的广泛应用阶段,该阶段提出了用该方法预测未来地震动的一般步骤,标志着用经验格林函数方法预测未来地震动,为建筑物的抗震设防提供依据已经到了比较成熟阶段。最后,对用经验格林函数方法和随机方法模拟地震动的优势和不足进行了比较。The ground motion simulation with empirical Green＇ s function has been developed for thirty years. It has became popular method of simulating ground motion. Through retrospection of history of this method, it is thought that the development of empirical Green＇ s function method can be divided into three phases ： the first is the phase that the theory of empirical Green＇ s function is established ; the second is the phase that the empirical Green＇ s function method is perfected gradually;the third is the phase that the empirical Green＇ s function method is ap plied broadly, generic steps of future earthquake prediction are put forward in this phase, this shows that future earthquake prediction and anti sesmic design of construction with empirical Green＇s function method are in more mature phase. At last, comparisons of advantages and disadvantages between empirical Green＇ s function method and stochastic method are made.
