Risk Analysis of Vessel-Bridge Collision Based on AASHTO Method

Abstract:

One bridge in the southeast coast was cited as an example and the risk analysis theory was introduced into the study of vessel-bridge collision problem of the bridge. From the survey of the current situation development in the bridge site area and 5000 tons collision-prevention requirements, the annual probability of collapse of the bridge in the year 2020 is over the criterion by the AASHTO model algorithm. In accordance with the AASHTO acceptance criteria for vessel-bridge collision risk, the mentioned vessel collision risk of the bridge was not acceptable. In this paper, based on “m” method and FLAC3D program, the research on horizontal bearing capacity of pile group of one bridge in the southeast coast under vessel impact is performed, and the effects of the anchor is considered, which is significant for the risk analysis and bridge anti-collision study.
