On the basis of summing up the characteristics of water level and the channel where the bridge is located of Huanghuayuan Jialing River Bridge of Chongqing City, the risk of ship collision and structural characteristics were analyzed with the advanced risk analysis methods of AASHTO method and integral path methods with three probability parameters. The pier protection measures raised on this basis include that P1 pier is designed with anti collision pier and in the design of P2 pier, the floating anti collision box programs based on the highest water level and the anti collision pier program are raised and a comparatively studied. These conclusions provide some references for the anti collision design of bridges under similar environments.
