Embodiment Construction

[0016] In order to make the technical means, creative features, goals and effects of the present invention easy to understand, the present invention will be further explained in the following in conjunction with the specific implementation of the navigation safety risk assessment of the waters of the Shanghai Port and Bridge District. figure 1 It is a flowchart of the navigation safety risk assessment in the bridge area of ​​the present invention.

[0017] 1. Design a water traffic safety risk assessment index scale and conduct data collection

[0018] According to the current situation of bridge water safety and management, domestic and foreign bridge ship collision accidents and impacts, etc., the hazard sources of bridge ship collision are identified and analyzed, and the navigation safety risk factors in the waters of the bridge area are formed; the specific items and classification of the risk factors are as follows figure 2 As shown, I will not repeat them one by one.

Abstract

The invention provides an evaluation method based on a bridge waterway ship navigation safety risk evaluation model. Bridge waterway ship navigation safety risk factors which are graded are listed in a risk evaluation index scale and scored by a professor; after weights of indexes are calculated through an AHP method and a VCM method, combination weighting calculation is carried out through a CWM method, and accordingly the difference between the weight calculated through the AHP method and the weight calculated through the VCM method can be eliminated; the weights calculated through the methods are subjected to consistency detection based on multi-element connection numbers; risk synthesis is conducted after second-level evaluation and first-level evaluation are performed, and bridge waterway ship navigation safety risks are correspondingly graded according to evaluation values generated after risk synthesis. By means of the method, hierarchical management is conducted on different bridges in the aspect of bridge waterway ship navigation safety management, the evaluation model is built to track and evaluate different bridges, and classification and hierarchical management is conducted according to evaluation results.

Description

Technical field [0001] The invention relates to the field of water transportation, safety science and engineering, and in particular to an evaluation method based on a navigation safety risk evaluation model of a bridge area. Background technique [0002] With the continuous increase of bridge construction and the rapid development of shipping, the incidence of ship collisions with bridges is on the rise. On average, about one large bridge collapses or suffers severe damage due to ship collision each year. In China, cases of bridge collapse or serious damage caused by ship collision are also frequent. The ship collision accident is extremely harmful, causing huge economic losses and casualties, as well as severe political impact and serious environmental losses. Summary of the invention [0003] The purpose of the present invention is to provide an evaluation method, by constructing the navigation safety risk assessment model of the bridge area water area, realize the navigation...
