A comprehensive protection method and system for the operation safety of a road-rail leveling bridge

Abstract

The invention relates to a comprehensive protection method and system for the operation safety of a road-rail leveling bridge. The invention provides an alternative when the height of the anti-glare board exceeds the height threshold, and replaces the anti-glare board with an anti-throwing net or a wind barrier, so that the anti-throwing net or the wind screen has an anti-glare function, and realizes the road-rail bridge The comprehensive protection of windproof, anti-glare and anti-throwing of operation safety has filled up the blank of comprehensive protection for the operation safety of highway-rail level bridge; It fills up the gap in the prior art that there is no evaluation method for the anti-glare performance of the anti-throwing net and the wind barrier.

Description

technical field [0001] The invention relates to the field of comprehensive traffic protection, in particular to a method and system for comprehensive protection of the operation safety of a highway-railway leveling bridge. Background technique [0002] The road-rail dual-use bridge is one of the most economical types of bridges in the world, and it conforms to the principles of environmental protection, energy saving, and sustainable development of human survival. In the highway-railway leveling bridge, the horizontal distance between the railway and the highway is very close. Due to the high speed of the high-speed train, the high intensity of the headlight and the strong concentrating, it will cause a light field, local wind and sea area when the train passes by. Crosswinds, etc., these complex environments may adversely affect the driving comfort and safety of vehicles on adjacent highways, and even cause traffic accidents. Therefore, it is necessary to analyze the local...

AI Technical Summary

Problems solved by technology

[0015] The existing regulations require that the height of the anti-glare board should not exceed 2m, but the light intensity of the railway light source of the highway-rail level bridge is strong, and when the horizontal distance between the highway and the railway is small, the calculated height of the anti-glare board often exceeds the specification requirements, but the existing methods do not give corresponding solutions and alternatives

[0016] (2) All kinds of protective facilities between highways and railways have certain compatibility and substitution. For example, wind barriers, anti-throwing nets and other facilities also have certain anti-glare performance. It is necessary to comprehensively consider and propose a protective facility plan, but there is currently no method to evaluate the anti-glare performance of wind barriers and anti-throwing nets, and there is no comprehensive protection method for the operation safety of highway-rail level bridges
