| 摘 要： | In this paper,the equivalent force inside the source which produces a large area deformation field is calculated by using the records of residual deformation,S wave radiation of shear dislocation source and Green function of the Lancang-Gengma earthquake.Under the action of equivalent force whose intensity was 1.103×1013 N,the crust derm of northeast segment of seismic fault had finished the upraise and formed permanent irrecoverable deformation within 20.46 min after the major earthquake occurred.The authors indicate that the residual deformation would split into 2 deformation fields with different propagation velocities and different directions in the Song-distance propagation process.
