摘　　要：为了准确掌握渭河断裂在咸阳吴家堡附近的浅部特征,根据研究区自然条件和城市道路、居民点分布等实际,采用现场钻探为主,地震勘探为辅,二者相结合的方法,对渭河断裂在场区内的分布位置、形态特征、类型及活动性进行探查和分析评价。研究结果显示吴家堡附近渭河断裂面南倾,倾角约50°～65°,为一张性正断层。断面浅部垂向错动距离约30 m,推算错动的平均速率为0.17 mm/a。In order to accurately master the shallow features of the Weihe fault in the vicinity of Xianyang wu- jiabao, according to the natural conditions, urban road and residential distribution of the research area, both meth- ods of the spot drilling and seismic exploration are adopt , in which mainly using the former, assisted by the latter, to do exploration, analyses and evaluation of the Weihe fault in the field area＇ s distribution, morphological charac- teristics, types and activity. The research result indicates that the Weihe fault surface which is close to the Wu- jiabao tilts to the south, the dip angle is about 50~ - 65~, which is a extension normal fault. Fracture surface＇ s su- perficial part＇ s vertical dislocation distance is about 30 m, calculating the dislocation＇ s average velocity is 0. 17 mnl/a.
