摘要
2008年汶川MS8.0地震有感地区范围大于1 000km。甘肃省十五期间在兰州市架设了50个强震台站用于实现市区范围内的强震动烈度速报,在本次地震中大多数台站都记录到了相应的强震动记录,其中最大单道加速度峰值记录为40.4cm/s2。本文展示了43个兰州烈度速报台站记录到的共129道本次地震强震动记录信息,并初步分析了兰州市加速度峰值分布和加速度峰值与土层厚度的对应情况。
The Wenchuan MS8.0earthquake in 2008caused shake even in region more than 1 000 km away.Most strong ground motion stations in Lanzhou area,which were built in＂tenth 5-years pla＂n for rapid reporting of seismic intensity,recorded seismic wave during the event,the maximum peak acceleration of single channel was 40.4cm/s2.In this paper,129records from 43 stations among total 50stations in Lanzhou area during the earthquake are shown.The distribution of peak accelerations in Lanzhou area and relationship between the peak acceleration and soil thickness are analyzed also.
