Material is identical, so that it is guaranteed that each several part stress equalization of bridge 200.
In the present embodiment, the purpose that each bridge tower both sides are respectively provided with secondary suspension cable 270 is in order in the bridge of super-span
Liang Zhong, reduce the pressure of bridge tower beam section 222.
In the present embodiment, tail rope 240 is respectively arranged between the first bridge tower 210 and the second bridge tower 212 and
Beam section 224 in main span between two bridge towers 212 and the 3rd bridge tower 214；Master between the first bridge tower 210 and the second bridge tower 212
In span centre beam section 224, the both ends of tail rope 240 are set relatively with the first middle interconnecting piece 263 and the second middle interconnecting piece 264 respectively
Put, so as to balance pulling force of the first inner side drag-line 236 to girder 220；Therefore the quantity of tail rope 240 in the present embodiment
It is five.Similarly, be in beam section 224 in the main span between the second bridge tower 212 and the 3rd bridge tower 214 tail rope 240 setting and

Material can also be other, it is not limited to carbon fiber, such as steel strand wires.
Bridge 200 combines the force-transfer characteristic of traditional cable-stayed bridge and suspension bridge, and traditional suspension cable is replaced by using suspension cable,
To change main push-towing rope power transmission mechanism so that main push-towing rope does not produce shear stress.Theory analysis shows：With compared with span tradition suspension bridge,
Main push-towing rope magnitude of maximum shearing stress drops to 10 from 14.2-4Magnitude, it efficiently avoid the appearance of shear stress.Meanwhile the beam section in main span
224 setting tail ropes 240 effectively reduce the axle power of cable-stayed bridge main-beam 220, and FEM model, numerical value point are established using MADIS softwares
Analysis shows：Compared with traditional cable-stayed bridge, under the conditions of identical tower height, when the length of tail rope 240 reaches main span half, girder 220
Middle axle power can reduce about 66%.
In the present embodiment, the material of main suspension cable 230, secondary suspension cable 270 and tail rope 240 is carbon fiber, and carbon is fine
The use of dimension material can make bridge 200 have more large span, and theoretical calculation shows：When sag ratio takes 1/10, factor of safety takes 2
When, traditional suspension bridge limitation span by the use of high tensile steel wire as main push-towing rope is about 8300 meters；And drag-line is used as by the use of high-strength carbon fibre
The limitation span of bridge 200 be about 72000 meters, 8.8 times of about traditional Suspension Bridges.
Compared with traditional long-span bridge, bridge 200 has more preferable economic benefit.Calculating shows：With traditional wirerope oblique pull
Bridge ratio, when across footpath is more than 1700 meters, the system of bridge 200 has more preferable economic benefit；Compared with traditional wirerope suspension bridge,
When across footpath is more than 2600 meters, the bridge 200 has more preferable economic benefit.
Represented to simplify, part is not referred in the present embodiment, refers to corresponding content in embodiment 1.
The present embodiment additionally provides a kind of construction method of bridge 200, refers to Fig. 4, Fig. 5, comprises the following steps：
Step 1, construction bridges basis, that is, build the first anchorage 250, the second anchorage 252, the first bridge tower 210, the second bridge
The bridge tower 214 of tower 212 and the 3rd；Bridge tower is using steel and concrete combined structure in the present embodiment, in other embodiments
Bridge tower can also use concrete structure；
Step 2, the lifting of bridge tower beam section 222 is carried out using cantilever-construction, install and draw and set secondary suspension cable 270；This reality
A middle girder 220 is applied using Plate of Flat Steel Box Girder；The section of girder 220 is lifted, and draws and sets secondary suspension cable 270, both alternately enter
OK, building for oblique pull region is completed；
Step 3, respectively between the first bridge tower 210 and the second bridge tower 212, the second bridge tower 212 and the 3rd bridge tower 214 it
Between lift main span in beam section 224 the section of girder 220；Then from middle part respectively to the side of the first bridge tower 210 and the second bridge tower 212
Built to, the direction of the second bridge tower 212 and the 3rd bridge tower 214, lifting girder 220 section, and draw simultaneously and set tail rope 240
With main suspension cable 230, repeat above procedure, until in main span beam section 224 respectively with the first bridge tower 210 and the second bridge tower 212, the
Two bridge towers 212 join the two sections of a bridge, etc with the 3rd bridge tower 214, complete building for suspension cable region, are finally completed building for bridge 200.
In this construction method, in addition to the embodiment of step 3, bridge can also be realized using other embodiments
Beam is built, referring to Fig. 6, for example：
After the building of above-mentioned steps two is completed, drawing sets main suspension cable 230 and tail rope 240, then lifts the first bridge tower
210 and the second main span between bridge tower 212, between the second bridge tower 212 and the 3rd bridge tower 214 in the girder 220 of beam section 224 save
Section, building for the avris region of beam section 224 in main span is realized, while draw and set tail rope 240 and main suspension cable 230；Respectively from first
The bridge tower beam section 222 relative with the 3rd bridge tower 214 with the second bridge tower 212, the second bridge tower 212 of bridge tower 210 lifts girder to middle part
220 sections, drawing set tail rope 240 and main suspension cable 230, complete building for beam section 224 in main span, are finally completed bridge 200
Build.
