ANALYSES OF CLIP BOLT
FRACTURE FOR GUARD RAIL OF RAILWAY BRIDGE |

Abstract: | A lot of deteriorated events have been taken
place since prestressed concrete ties are employed in railway bridge,and clip bolt
fracture is one of such events.By means of establishing mechanical analyzing models,the
causes for clip bolt fracture are investigated and the countermeasures of reducing the
clip bolt fracture are presented in this paper. |
