摘要场地地震反应分析是地震工程的重要构成成分之一，它的计算结果为抗震设计提供设防根据，具有重要的工程价值。场地地震反应分析方法一般情况下分为为等效线性化方法和非线性方法。等效线性化方法的优点是原理简单、参数易于选取、小震正常场地剖面下结果合理，等效线性化方法现在已得到广泛应用。可是它的“放大低频，低估高频”的不足影响到了它在复杂土层结构场地和大型地震情况下结果的准确性。而非线性方法则更加接近现实情况，但因为其参数选取困难，一般仅为专业人士掌握，工程应用不多，需要对非线性程序的使用方案进行研究。87102

ABSTRACT Site seismic response analysis is one of the important components of earthquake engineering, and its calculation results provide a design basis for the design, which is of great significance in engineering。 The method of site seismic response analysis can be pided into equivalent linearization method and nonlinear method。 Equivalent linearization method has the advantages of simple principle, easy selection of parameters, and reasonable results under small earthquakes。 It has been widely used。 But its ‘amplification of low frequency, underestimate the high frequency’ of the shortcomings of its impact on the accuracy of the complex soil structure site and the results of large earthquakes。 Fly linear method is more close to the actual, but because of its parameter selection difficult, usually only for professionals to master, engineering application is not much, need to study the use of nonlinear program。 

The Yuejin Village of actual geological situations and 6 groups provide the bedrock seismic wave based on using seismic response analysis program SHAKE91 software for a large number of numerical calculation and plot and comparative analysis。 Through the mutual contrast under various conditions of different site seismic response analysis results, reflecting the information Yuejin Village specific site seismic response analysis。
