Abstract：Using analog data and measured GPS velocity field, we analyzed the influence of different fault dip angles, different weight f and data spatial distribution on the negative dislocation inversion program of Defnode. The inversion results of analog data show that the inversion results both have a high degree of reliability under conditions of low dip angle and high dip angle.Measured GPS velocity field inversion results of the Longmenshan fault zone show that they have good stability and the weight f has little influence on the inversion results, and the distribution of GPS observation stations (especially the quantity and location of stations near the fault zone) has certain influence on the inversion results, but it can not change the fact that the southern segment is a little less locked than the middlenorthern segment.
