【摘要】 我们采了19个沂沭断裂带断层泥样品,测定了断层泥样品三个方向(x,y,z)上的纵波速度(Vpx,Vpy,Vpz)。其中x为断层走向,y垂直于断层面,z为铅直向。根据测量结果表明,该区的大震危险性趋于减小。更多还原

【Abstract】 We got 19 natural samples of fault gouge from Yishu fault zone and measured the longtudinal wave velocity (Vpx, Vpy, Vpz) of the fault gouge samples along three directions (x, y, z). Here: x is fault strike; y is perpendicular to fault surface; z is the plumb line. It is indicated by the above results of measurements that the seismic risk of the region is gradually decreasing.更多还原
