| 摘 要： | 本文利用近场理论格林函数反褶积的方法计算土层的地震反应.解答中包含了产生地面运动的各种反射、透射和转换波震相,也计入了土层与基底介质的相互作用.将计算的土层响应与已获得的近场加速度记录褶积,可算出不同土层场地上垂直向和水平向三分量的地面运动.文中利用1982年卢龙地震的近场加速度记录,检验了方法的可行性.

| Abstract: | The site effects on strong ground, motion is very important. For estimating the ground motion at site with different, conditions to use the near-field seismic records as the incident wave, a method of computing soil's response by the deconvolution of the theoretical Green functions is presented. It solves the problem that only the response of the planar incident waves are computed in preious studies, and the three-components of ground motion can be computed by the convolution of the computed soil's response with the strong motion records. This technique is used to comput the ground motion of the Lulong earthquake at stations TS02 and TS09, from the acceleration records at station TS12. The good fit of the computed results with the data demonstrates the validity,of this approach. |
