Abstract：Inthefieldof safeoperationof river-crossing bridges，thepreventionandcontrolof vessl colisionrisks areof great significance toensure traffic lifeline and public safety.This study focuses on the vessel colisionrisk analysis andanti-colisionfacilityoptimizationofariver-crossng bridge.Byanalyzingthe bridge structure parameters，navigation environment characteristics and pier exposure，the risk asessment model construction，collsion probability calculation and structural failure risk quantification are systematically expounded.The results show that thelayered design effctof stel-compositecomposite anti-collsion facilities optimization isobviously improved， and the matching valueof risk distribution and protection scheme is clarified.Itcan provideoperable risk preventionandcontrolreference for bridge engineering practitioners，help thedevelopmentofanti-collision technologyof river-crossing bridges，and promote and realize the goal of safe operation of bridges.
