| 摘 要： | 在数字观测资料基础上发展起来的地震动随机模拟方法，能较客观地把研究区的震源特性、传播路径影响和场地响应考虑进来，适用于缺乏强震记录的国家和地区。但在实际应用中，有不少关键问题尚未解决，其中，软基岩的场地响应是地震学家一直想解决但始终没有很好解决的问题；另外，厚覆盖土层的场地响应是工程上很关心的问题，由于资料和方法限制，研究工作做的很少；而强震的震源谱对地震动随机模拟结果影响显著，一直都是随机模拟方法的研究焦点。总之，这两个方面的3个问题都是地震动随机模拟方法应用中的“关键问题”，本文在大量的研究工作基础上，对这些关键问题提出一些探讨性的解决途径和方法。

| Abstract: | The stochastic simulation of strong ground motions developed on the basis of observation data, can objectively consider the factors such as focal mechanism, propagation path and site effect. The stochastic method is applicable for the countries or regions which lack of strong ground motion records. But there still are some key problems such as the site effect of soft rock or thick soil cover, and the effect of source spectrum on the simulation. On the basis of analysis and study on these problems. An exploring approach to solve them has been suggested. |
