【摘要】 本文分析了主形变带和地震形变带与老断层面的关系,指出主形变带与地震形变带不能简单地看成一致或重合,二者是随时空变化的。把断层形变测线布置在地震形变带最大剪切形变段上,不一定能测到断层带上平时的最大剪切形变值。鉴于鲜水河走滑断层两盘同时运动的事实,建议把形变测线布置在老断层带非闭锁段上,并向两侧延长80—100m。更多还原

【Abstract】 The relation of the principal deformation zone and seismic deformation zone to the old fault sur face is analysed in this paper. It is indicated that the principal deformation zone and the seismic defor mation zone cannot be simply considered to be identical or overlaping, and they change with the time and space. It is uncertain that the maximum shear deformation in fault belt is measured by setting the deformation measuremant line on the maximum shear deformation section of seismic deformation zone. In view of the simultaneous motion of the strike slip fault on both sides of the Xianshuihe, it is proposed that the deformation measurement line should be arranged in the unblocking section of the old fault and extended to 80--100 m from both sides.更多还原
