| 摘 要： | 根据普洱、 西双版纳地区6个地震观测台站在2008——2009年获取的5级以上的地震资料， 利用接收函数和面波衰减系数， 反演得到了研究区域的S波速度结构和Qβ结构. 基于该结构模型， 采用随机振动理论方法， 预测了2007年宁洱MS6.4地震发生后， 在震中距为10——300 km范围内引起的地面运动， 并借助获取的强震观测记录检验、 评价了该预测结果. 同时， 将地面运动预测结果与利用回归衰减公式计算得到的结果进行对比， 进而讨论该地震动预测方法在地面运动预测中的可行性． 结果表明， 该预测结果与实测结果吻合．

| Abstract: | Seismic records of M>5.0 earthquakes during 2008 to 2009 were acquired at 6 seismic stations in Pu’er and Xishuangbanna regon.We obtained S-wave velocity structure beneath these stations by receiver function analysis and Qβ model from attenuation coefficients of surface waves.Based on the resulted velocity model,we evaluated the relationship between peak accelerations and epicentral distances,ranging from 10 to 300 km,for the 2007 Ning’er earthquake with random vibration theory method.Through comparing the predicted peak ground motion with that calculated from regression attenuation formula,the feasibility of the used prediction method is discussed.The comparison shows that the two results are consistent,indicting the predicted ground motion being reasonable. |
