项目摘要
A method for the identification of the damping parameter(Quality factor) in subsurface ground using array records of ground motions is developed. The ground motions have been recorded at observation stations of KiK-net which is employed by NIED(National Research Institute for Earth Science and Disaster Prevention). The records of ground motions, which are corrected for the azimuth error of bottom sensors as well as surface sensors, are used in the identification. The identification is carried for the observation stations which are regarded to be appropriate by field investigation. Accumulating the results of identification, the trends of the frequency dependency of quality factor are extracted and quality factor of frequency non-dependent type is modeled.
本文提出了一种利用地震动台阵记录识别地下介质阻尼参数(品质因子)的方法。在NIED(国家地球科学与灾害预防研究所)雇用的KiK-net观测站记录了地面运动。在识别中使用了地面运动记录,该记录对底部传感器以及表面传感器的方位误差进行了校正。对野外调查认为合适的观测站进行了识别。累积辨识结果,提取品质因数的频率相关性趋势,并对非频率相关型品质因数进行建模。
