Teleseismic travel-time tomography has made great progress in recent decades,and many achievements have been obtained in the study of inversion of underground structures. Due to the poor coverage of rays under the stations,the remote seismic inversion method has the problem of insufficient restriction on crustal velocity. In this paper a new crustal anomaly correction method is proposed,in which the relative travel time residuals of the same station are summed up and averaged,and the complex velocity anomaly bodies in the crust are eliminated for the inversion of upper mantle velocity structure. Our results are of relatively better relative travel time residuals,as well as the smaller data error.
