| 摘 要： | 根据线性滞回阻尼理论和土层的频域本构关系,以Matlab为平台编制了计算机程序,对水平成层土的暂态地震响应进行了频域内的反演,从而利用土层特性和地面地震动时程得到了地层深处的地震动时程,并在数值实验中采用SHAKE91程序进行正演验证。算例分析结果表明,该反演方法能够较好地模拟出地层深处的地震动时程。

| Abstract: | Based on linear hysteretic damping theory and frequency constitutive equation of soil layer,the computer program is worked out with Matlab as the plateform to carry out the inversion of frequency domain for the transient seismic response of horizontal stratified soil,whereby the seismic acceleration time-period of interior stratum can be obtained using soil layer behaviors and ground seismic acceleration time-period.Also,SHAKE91 programming is adopted in the numerical experiment to carry out the positive tests.The analytical results from the calculation examples indicate that this inversion method can better simulate the seismic acceleration time period in the deep stratum. |
