Problems solved by technology

With the development of waterways and bridges, there are more and more accidents of ships colliding with bridges, and the impact of accidents is also increasing. From the perspective of navigation, the construction of bridges not only limits the passage capacity of waterways, but also increases the navigation of ships. risk
Therefore, in order to accurately grasp the navigat

Abstract

The invention discloses a navigation risk evaluation method for a bridge. The method comprises the following steps: building a ship motion mathematic model, and building a ship and bridge collision probability mathematic model based on the ship motion mathematic model through employing the design size of the bridge, a passing ship type, a bridge region air flow navigation condition and ship flow as risk factors of the collision between a ship and the bridge; and establishing a navigation risk grading standard corresponding to the collision probability of the ship and the bridge, and evaluatingthe navigation risk of the bridge by applying the mathematical model of the collision probability of the ship and the bridge. The navigation risk can be quantitatively evaluated in the design stage of the bridge, so that the ship safety of the water area of the bridge area is guaranteed.

Description

technical field [0001] The invention relates to the field of water transportation, in particular to a navigation risk assessment method for bridges. Background technique [0002] The foundation of water transportation is the waterway, which is an important public welfare transportation infrastructure of the country and is a limited non-renewable resource. As of the end of 2018, the navigable mileage of inland waterways nationwide was 127,100 kilometers, ranking first in the world, with 66,400 kilometers of inland waterway grades, of which 13,500 kilometers were third-grade and above waterways, basically formed with the Yangtze River trunk line, Xijiang shipping trunk line, Beijing-Hangzhou Canal, The waterway network of the Heilongjiang River System, the Yangtze River Delta, and the Pearl River Delta is a waterway network with direct branches and rivers and seas as the backbone. With the development of waterways and bridges, there are more and more accidents of ships collid...
