摘要
通过在结构内外两对应点实测的多对记录来计算两点间的传递函数。对给定的爆破设计，首先预测结构地基波形，然后利用地基波形与传递函数在频域内乘积的Ｆｏｕｒｉｅｒ逆变换来预测结构响应，其预测结果与实测结果基本吻合。
The transfer functions between two points are calculated using some pairs of recordings obtained by actual measurement of the two corresponding points inside and outside a building. For a given blasting design, the waveforms of ground vibration are predicted before the responses of buildings are predicted by inverse FFT of the product of ground waveforms and transfer functions in frequency domain. Its predicated results are about the same as its actual results.
