| Abstract: | According to the current status that the anchor seal frequently exfoliates from the anchor seal concrete of the unballasted track plate,the paper researches the post-tensioning prestressed anchor pit chiseling machine according to the results of the dynamic analysis,indicates the ring channel flow can be formed automatically in the anchor pit,so it can improve the bond strength between the anchor seal concrete and the anchor pit,and also provide the effective ensurance for the durability of the prestressed system. |

| Keywords: | prestressed anchor pit pre-shiseling machine ring channel dynamic analysis implementation scheme |
