- Abstract:
- Using the acceleration peaks of 64 stations and the strong earthquake waveform data of 10 stations in the area around the epicenter of Qinghai Menyuan MS6.4 earthquake,we analyzed the attenuation of ground motion,the acceleration response spectrum and the ratio of vertical component and horizontal component. The research results show as follows:the ground motion attenuation law of Menyuan earthquake basically accords with that in Tibetan area. When the epicenter distance is within 300 km,the attenuation speed of horizontal and vertical ground motions are close; when the epicenter distance is greater than 300 km,the attenuation speed of horizontal ground motion attenuation is slower than that of the vertical ground motion. When the epicenter distance is within 200 km,some stations with larger PGA ratio of UD/NS are basically distributed in the north area of Lenglongling Fault and Tuolaishan Fault. Compared analysis on the three-component of acceleration response spectrum,we find that compared with bedrock site,the soil layer site presents obvious site amplification effect. The groove phenomenon of response spectrum shows that the role of vertical ground motion should be paid attention to the engineering earthquake resistance.
