Abstract：The particle swarm algorithm is a newly developed optimization. Application of the particle swarm algorithm in geodetic inversion problems is rarely reported in China. In this study, by using the particle swarm optimization algorithm combined with the dislocation model，the three dimension slip velocity of the Qilianshan mountain fault is inversed by using leveling data observed in Hexi region during 2001-2004.The results show that the particle swarm optimization algorithm can compute three dimension slip velocity of the fault effectively. The results of the numerical inversion are consistent with those obtained by geological methods.
