【摘要】 分析了汶川8.0级地震前后的关中垂直形变及陕西地区地倾斜变化特征。结果表明:震前,跨断层垂直形变表现出阶段性变化特征,南大同、大塬、涧峪口、清河口、口镇等场地的垂直形变出现了明显的趋势转折、加速变化。汉中、宝鸡、乾县、西安台的地倾斜潮汐因子γ存在3个月左右异常变化。更多还原

【Abstract】 The characteristics of vertical deformation in Guanzhong area and the ground tilt in Shaanxi province are analyzed.The results show that the vertical deformation appeared periodic,tendency turning and acceleration variation in Nandatong,Dayuan,Jianyukou,Qinghekou,Kouzhen;the tidal factor γ of ground tilt appeared anomalous variation about three months before Wenchuan Ms 8.0 earthquake.更多还原
