摘    要:目前在中、美两国场地土层地震反应分析中,应用比较广泛的计算软件为ESE和SHAKE,两者均采用频域等效线性化方法处理非线性的土层动本构关系。本文采用上述软件分别对三种典型场地进行计算,分析两者差别及造成差别的原因。研究结果表明,SHAKE软件在深软场地时,计算反应谱和加速度峰值均与实际统计结果差别较大,不适合工程应用。ESE软件计算结果比较合理。

关 键 词:频域等效线性化分析方法  ESE软件  SHAKE软件  反应谱

Abstract:At present, ESE and SHAKE procedure are widely used to seismic analysis for soil layers in China and the United States of America. These two procedures both use the one-dimension equivalent linear method to deal with the nonlinear soil dynamic constitutive relationship. In this paper, we calculated respectively three typical profiles though ESE procedure and SHAKE procedure. The result shows that SHAKE procedure can't get more reasonable PGA and response spectrum values when the soil profiles are deep or the input ground motions are strong. The ESE procedure can be used in engineering well.
Keywords:frequency domain equivalent linearization analysis method  ESE procedure  SHAKE procedure  response spectrum
