非平稳人造地震动反应谱拟合的震记录应用研究

         

摘要

利用天然地震记录数据提取其非平稳相位数据的方法、论证人造地震动方法的可行性和合理性,并以呼和浩特市基岩场地非平稳人造地震动预测拟合应用为例,进行人造地震动反应谱拟合.本研究方法明显加强地震监测数字化记录与结构地震动输入预测模拟的密切联系,使地震动预测因充分利用近场地震观测资料而得到质的飞跃.%In this paper, with the method of extracting non-stationary phase data from natural seismic record, the feasibility and rationality for artificial ground motion record method are demonstrated. As an example, the new method is applied for generating the non-stationary artificial ground shocking at the rock site of Huhhot city area which to pick up the non-stationary phase of natural seismic record from the feel earthquake for the response spectrum compatible. The method makes more strong relationship between the digital record of seismic observation and the ground strong motion evaluation of structure. And this evaluation has been a qualitative leap.
