	Dipole field kicks arisen from the construction and alignment of the magnets may cause the orbit distortion and reduce the efficiency of beam extraction and striking target in RTBT transport line of CSNS. In this paper, orbit correction is done based on XAL Orbit Correction application with the algorithm modified partially and the result was according with by AT toolbox. Meanwhile, the orbit correction before the target was special considered for the beams striking the target center vertically.
