Radiation forces and trapping stability of metallic (i.e. gold) Rayleigh particle by combined beam are analyzed, and the combined beam is formed by superimposing two partially coherent off-axis flat-topped beams. The dependences of radiation forces on off-axis distance parameter, correlation length and particle radius are illustrated by numerical examples. The results show that there exist critical values d 0,cand σ 0,c for the combined beam. For 0
