通过对华北地区洞体应变、钻孔应变以及倾斜观测资料的统计分析,将尼泊尔M_S8.1地震引起的同震波动幅度和初动方向进行了归纳总结,并与其它观测手段的结果进行对比分析。结果表明:华北地区应变观测资料的EW向压性初动主要集中在EW向的断裂附近,张性初动变化则主要集中在NE向的断裂附近,NS向同震变化主要是以张性初动为主;华北地区倾斜观测EW向的同震变化主要是以西倾初动为主,NS向的同震变化主要是以南倾初动为主,反映了尼泊尔强震震中以北地区向南运动的弹性响应过程。
Based on the statistical analysis of cave strain, borehole strain and tilt observation data in North China, the coseismic amplitude and initial direction induced by M_S8.1 earthquake in Nepal are summarized and compared with the results of other observation methods . The results show that the EW compressive initial motions of the observed data in North China mainly focus on the vicinity of the EW fractures, while the initial changes of Zhang are mainly concentrated near the NE fractures. The crescentic variability in the NS is mainly dominated by the onset of tension. The crescentic variation of the EW trending in North China is mainly dominated by the western overthrow of the initial incrustation. The NS coseismic coseismic changes are mainly dominated by the south declination and reflect the elastic response of the Nephrology northward to the epicenter process.
