Description
Technical field
The invention belongs to Design of Traffic Safety technical field, and in particular to one kind be applied to Loads of Long-span Bridges on can with bridge
The Novel moveable air partition that driving vehicle is synchronized with the movement.
Background technology
Because China is vast in territory, climate variability, traffic safety is by a variety of inside even from weather.Wherein mountain pass, bealock, height
The influence of the section generally existing strong black holes such as roadbed bend, Longspan Bridge.Wind in natural environment, it is to influence the traffic such as automobile
One important extraneous factor of instrument riding stability and security.For the vehicles, main hazard is effect of Side Wind.
, there is the report that crosswind causes vehicle to topple in the multiple coastal cities of typhoon every year, and the phenomenon is particularly acute on bridge.Side
Wind has a great impact for the stability of vehicle, because will produce power of toppling when wind-force exceedes certain numerical value, causes car
Topple or slide, cause the generation of traffic accident, cause very big potential safety hazard.Therefore crosswind is improved to traffic safety
Influence is extremely necessary.
When meeting with typhoon, government often selects enclosed bridge to ensure the safety of bridge and vehicle.This political affairs
Although plan ensure that the safety of vehicle, but also cause two regions of bridge connection to form isolation.By taking Xiamen as an example, stepped in typhoon
Lu Shi, if completely enclosed bridge, will cut off the connection on the main island in Xiamen and hinterland, make the main island in Xiamen be isolated from the outside, tall building
The indispensable living material on Men Zhu islands is difficult to normal transport, and the material stock on main island can not meet the isolation of more days.Therefore how
Cause bridge normal pass during typhoon, ensure the necessary transportation function in basis just into needing to solve the problems, such as.
It is unusual one of effective measures that protection from the wind is set in the multiple area of crosswind, especially sets air partition in bridge spanning the sea
It is very common.There is more achievement in the research of Wind-resistance of Bridges, to discussions such as the forms, height, porosity of bridge air partition
It is more.Traditional bridge air partition is divided into two kinds of continuous air partition and local air partition, although continuous air partition comparison is effective, cost performance compared with
It is low, relatively guard；Although and local air partition can guarantee driving safety in most cases, running into accidental effect of Side Wind
When it is difficult to ensure that the performance of its function, reliability are relatively low.Traditional most important problem of air partition also includes installation and built and later stage dimension
Protect it is more complicated, while it is the most serious the problem of be that the installation of air partition can additionally increase very big to bridge (especially suspension bridge)
Cross force load so that the failure probability of bridge greatly improves, and faces bigger safety and economic hidden danger.
In conventional research, it is less to be related to moveable local air partition safety devices.It is moveable applied to Loads of Long-span Bridges
New air partition, there is high performance-price ratio, high-reliability, and it is small to additional lateral load caused by bridge, it is an existing practical valency
Value has far-reaching invention to study again.
