【摘要】 <正> 一、引言地震成因研究表明,绝大多数地震属于构造地震,而构造地震的发震构造主要是活动断层.因此对于活动断层进行跨断层形变测量,是地震预测、预报和地壳稳定性评价的常用监视手段之一.目前在地震带、构造活动区的一些活动断层上布设了跨断层测量的点、站,进行水准和基线测量,其中有些点、站设在隐伏断层上.为了提高测量效果,在满足更多还原

【Abstract】 There are measuremant stations across the main faults in seismic belt or seismic region. But Some measurement stations set up at hidden faults. For fault plane is decline, fault projection towards ground surface is two fault line in thin covered area. One fault line is fault top by projection towards ground surface, another fault line is fault updip by projection forwards ground surface. The former line is fault line in geologic map, the latter line is fault deformation and displacement area. It is not measurement in thick covered area.更多还原
