Abstract: In this paper,according to the calculating formula for the surface displacements related to an inclined,shear and tensile fault,an inverse model of inclined fault has been established,by use of Segall and Harris＇method.A FORTRAN program has been given also,by which the deep slip rate and deep slip value of different attitude fault in different motion components can be inversed.So,the slip rate of two faults in Beijng area have been calculated.The activity of main active faults in Beijing area are well coincident with the regional stress field and fault stress field.

Key words: Geodetic deformation measurement, Inversion model, Fault slip, ault displacement rate

摘要： 根据倾斜断层走滑、倾滑及拉张运动产生的地表位移计算公式,利用Harris和Segall的反演方法,建立了倾斜断层具多个滑动分量的反演模型,编制了相应的计算机程序,实现了利用大地测量资料反演计算不同产状断层深部不同运动方向的滑动速率或滑动量。并以北京地区两条主要活动断层为例进行了计算,获得结果与北京地区区域应力场及断层应力场具有较好的一致性。
