Description
Technical field
The present invention relates to the stayed structures of cable-stayed bridge, and in particular to it is a kind of can electrified regulation parallel wire stay system.
Background technique
Along with the progress that modern science and technology are maked rapid progress, new material obtains exploitation and application, and construction method is changed
Into with perfect, the especially breakthrough and innovation of the fast development of computer technology and finite element method and analysis theories, make
The span ability for obtaining bridge is more and more stronger, wherein being the Large Span Bridges of representative even more as after rain using cable-stayed bridge, suspension bridge system
Spring bamboo achieves high speed development.The across footpath of suspension bridge is close to 2000 meters of magnitudes, such as 1624 meters of the big Bell's grand bridge main span of Denmark,
Japanese 1990 meters of alum strait Bridge main span.Cable-stayed bridge across footpath more than 1000 meters magnitudes, at present in cable-stayed bridge, Japanese is more
More Luo Qiao across footpaths are 890 meters, and Soviet Union's Changjiang River bridge span is up to 1088 meters, and Shanghai Changjiang River Main Bridge is across reaching 1092 meters.Arch bridge
Across footpath also reach 550 meters of magnitudes.Suspension bridge and cable-stayed bridge are to transmit load, half-through and lower bearing arch bridge by cable system
It is also required to transmit the primary load of girder by sunpender.Cable bears the entirety of the safety direct relation bridge structure of system
Safety is the key link during bridge construction so guaranteeing the safety of the cable bearing system of Long span cable bridge, significant.
Wind-induced vibration be threaten Long span cable bridge safety key factor: under eternal frost climate, due to icing object change suspension cable with
The cross sectional shape of girder forms unstable aerodynamic configuration, changes the aerodynamic characteristics of drag-line and girder, just probably draws
The flutter of bridge is sent out, whirlpool vibration, is buffeted and the charming appearance and behaviour such as galloping are shaken
In January, 2008, hazard weather sweep across Central China, and temperature continues at -5~-1 DEG C, and some mountain areas reach -7 DEG C；It is relatively wet
Degree is maintained at 90% or more；And it is accompanied by certain wind-force, large-scale sleet weather leads to electrical equipment large area icing.With
Unlike boreal climate, Central China's humidity is big, and sleet freezes in drop, and the appearance that can be attached on nudity immediately is not lost,
Form increasingly thicker, dense and solid ice sheet.Especially Hunan Province has met with rare ice damage.In cold environment, suspension cable
It is also easy to produce icing, icing will make the deviation of gravity center central axis of suspension cable, become unstable aerodynamic configuration.In addition, freeze
Ice cube is fallen under effect of vibration, is easy to injure pedestrian and automobile by a crashing object, brings security risk to the operation of bridge.
In order to solve the above problem, it needs to develop a kind of anti-freeze, deicing hot extruded polyethylene parallel wire stay system, prevents
Only suspension cable freezes in cold environments.
