| 摘 要： | 引入“结构动力学数值分析解析递推格式法”求解软土地基地震反应分析问题。就一维地基非线性地震反应分析问题，将解析递推格式方法与等效线性化方法在各种场地土的计算结果进行了比较，结果表明：(1) 对软土层地震反应分析时，两种方法计算结果差别较大； （2）入射波幅值较强时，两种方法计算结果差别较大；（3）对于中等硬度土层、入射波幅值较弱时，计算结果相似, 并验证了该方法的实用有效性。

| Abstract: | A digital algorithm-analytical recursion scheme method for the structural dynamics to solve the earthquake response problem of the soft clay foundation is put forwarded.From the outcomes of the research,the analytical recursion scheme method can obtain more accurate calculating results.It is a general numerical algorithm in nonlinear vibration problem,especially suits for the seismic response analysis of soft clay foundation.For one-dimension earthquake response analysis of soft clay foundation,a more sufficient comparison is taken between the analytical recursion scheme method and the(equivalent) linear method for the result of account in manifold ground.The outcomes show:(1) In the soft soil seismic response analysis,the difference between these two methods is relatively greater;(2) When the value of the inputting earthquake waves are greater,the difference between these two methods is relatively greater;(3)For the medium hardness soil layer earthquake waves was stronger,the two methods got similar results.The validity of the proposed analysis method and computer program has been verified. |
