利用模拟长周期地震动的显式有限元技术和并行计算技术、场地一维线性反演和等效线性化方法以及有限断层模型,针对一个具体的城市地下结构模型,本文给出了一套近断层地震动预测的方法和相应的预测结果,并与近断层地震动的特征对比,分析了预测结果的合理性。
Using the finite element method with parallel computional technique for simulation of ground motion with long period, the one-dimensional linear inverse method, the equivalent linearization method, and the underground structure of one city, we present a method: for pl-edicating the near-fault strong motion, and give the result of the city. By comparing the result with some characteristics of near-fault strong ground motion, we analyze the rationality of the result.
