Abstract:

A correlation-stack method is proposed to estimate the site effect in urban city and its accuracy is proved by simulated data. The method estimates the site-transfer-function from subway vibration data. It eliminates the disturbance of the other urban environmental vibration successfully, which offers a new approach for estimating the site effect.

Key words: site-transfer-function, subway vibration, urban environmental vibration

摘要：

为了在城市环境条件下获取场地振动响应特征, 提出一种互相关叠加方法, 并利用模拟数据验证方法的正确性。该方法利用地铁的地表振动记录确定场地传递函数, 能够有效地压制其他振动的干扰, 可以为获取场地传递函数提供一种新的方式。
