Highway-railway flat-layer bridge operation safety comprehensive protection method and system

Abstract

The invention relates to a highway-railway flat-layer bridge operation safety comprehensive protection method and system. The invention provides an alternative scheme when the height of an anti-glarepanel exceeds a height threshold value, and the anti-dazzle panel is replaced with an anti-dazzle net or a wind barrier, so that the anti-dazzle net or the wind barrier has an anti-dazzle function, wind-proof, anti-dazzle and anti-dazzle comprehensive protection for operation safety of the highway-railway flat-layer bridge is achieved, and the blank of comprehensive protection for operation safetyof the highway-railway flat-layer bridge is filled up. The invention further provides a method for evaluating the anti-glare performances of the anti-glare net and the wind barrier, and the blank that no method for evaluating the anti-glare performances of the anti-glare net and the wind barrier exist in the prior art is also filled up.

Description

technical field [0001] The invention relates to the field of comprehensive traffic protection, in particular to a comprehensive protection method and system for the operation safety of a road-rail level bridge. Background technique [0002] The road-rail bridge is one of the most economical bridge types in the world in terms of bridge design and channel resources. It conforms to the human survival principles of environmental protection, energy saving, and sustainable development. In the highway-rail 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 light concentration, it will cause a light field, local wind and sea area when the train passes by. These complex environments may have adverse effects on the driving comfort and safety of vehicles adjacent to expressways, and even cause traffic accidents. Therefore, it is necessary to analyz...

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
