摘要

利用场地大型振动台试验，基于传递函数理论，计算得到场地的相对传递函数和绝对传递函数，并对两类传递函数特征以及利用两类传递函数计算场地动力特性参数的差异性进行了对比，并对采用传递函数进行场地频域动力响应估算的可行性和准确性进行了分析。研究结果表明：相对传递函数和绝对传递函数的虚部重合，采用两种传递函数虚部计算场地动力参数具有等同性，且采用两种传递函数虚部曲线计算得到的动力特性参数较为准确；固有频率的计算适合采用两种传递函数的虚部或是相对传递函数的模；场地阻尼比的计算宜采用两种传递函数的虚部或绝对传递函数的模；利用两种传递函数实部、虚部或模计算得到的场地加速度振型是一致的；利用传递函数估算场地频域动力响应是可行的，且相对传递函数的估算结果更加准确。该研究对传递函数在场地动力特性参数计算及场地频域响应估算方面进行了有益的尝试。

Abstract

Through on-site large-scale shaking table tests

the transfer function theory is used to derive the relative transfer function and the absolute transfer function

and these two transfer functions are compared with regard to their characteristics and the adopted dynamic parameters

and then the feasibility and accuracy for estimating the frequency domain response are analyzed. It is shown that the imaginary parts of the two transfer functions are equal to each other

and the dynamic parameters estimated by using the imaginary part of the two transfer functions are the same. The imaginary part of the two transfer functions and the module of the relative transfer function can be used to calculate the natural frequency of site

while the imaginary part of the two transfer functions and the module of the absolute transfer function are suitable for the calculation of the damping ratio. The acceleration vibration modes calculated by the real part

imaginary part and module of the two transfer functions are the same. It is feasible to estimate the seismic response of site in the frequency domain by the transfer function and the relative transfer function yields better results than the absolute transfer function.
