Description
Technical field
The present invention relates to the only Cable-stayed Bridge with Slanted Pylon structures and construction method of a kind of active balance main span horizontal force, belong to bridge
Field.
Background technology
Cable-stayed bridge is by the indeterminate cable bearing system bridge of a kind of high order that suspension cable, girder and Sarasota three parts form
Beam, girder is to be pressurized or by based on curved, suspension cable is based on tension, and Sarasota is based on being pressurized.Cable-stayed bridge is big with its span ability,
The advantages that attractive appearance and structure novel, has become one of the bridge type most paid close attention to by engineering circles and researcher, and cable-stayed bridge can be divided into solely
Pylon cable-stayed bridge and multi pylon cable stayed bridge, and single pylon cable stayed bridge then bridge tower only there are one, since its economy and technical comparison are good,
There is stronger competitiveness in Short/Medium Span Bridge.In addition, solely Cable-stayed Bridge with Slanted Pylon as a kind of novel structural system bridge,
Stress is more complicated than only straight pylon cable-stayed bridge, to also determine their differences in structure design, rational structural system
Can not only cable-stayed bridge preferably be carried, shape is also more beautiful.
Conventional straight pylon cable-stayed bridge（Only tower or multitower）Often there is end bay beam and main span beam, dorsal funciculus power and main rope at this time
Horizontal direction component and girder axle power of the power in girder are balanced in tower pier beam intersection, and dorsal funciculus power and main rope power are square vertically along king-tower
To component and king-tower dead weight three's resultant force be transferred to bridge pier and pile foundation along tower axis direction, the general bridge pier of this cable-stayed bridge compared with
Height, basis is vertical pile foundation and is only vertical carrying, and stress is relatively simple, and shape is beautiful not as good as Cable-stayed Bridge with Slanted Pylon.And leaning tower
Cable-stayed bridge generally only has single bridge tower, and main span rope is only arranged, and both main span Suo Li and leaning tower dead weight resultant force are along leaning tower axis
Direction is transmitted, and horizontal components and girder axle power of the main span Suo Li in girder will be transmitted along girder axis direction, and in Ta Dun
Be balanced at beam consolidation, however the horizontal force in Cable-stayed Bridge with Slanted Pylon main span is often larger, can not complete equipilibrium, will deposit in main span
In uneven horizontal force, abutment need to be made very big at this time, to resist the shear action of uneven horizontal force, avoid inclining for bridge
It covers, and vertical pile foundation or a bit of girder of end bay side setting is set in abutment lower part, by end bay side girder axle power to offset
The uneven horizontal force of main span, bridge pier is shorter at this time, and it is only vertical carrying, both leaning tower oblique pulls that vertical pile foundation, which is arranged, in pier bottom
Bridge structure not only substantially increases quantities, and the characteristics of do not play the system attractive appearance.With design theory
Ripe and construction technology level raising, engineer constantly break through tradition, feel free to try, pioneer and invent, and increasingly pursue structure
Reasonable and appearance the grace of system is exactly one of which for the only Cable-stayed Bridge with Slanted Pylon system of full ground anchor type single span, outside the system
Graceful, structure novel is seen, the current country is built seldom, and in order to preferably solve the problems, such as main span imbalance horizontal force, promoting should
The extensive application of structural system, it is vital to seek more rational stress system.
Invention content
In view of the deficiencies in the prior art, technical problem to be solved by the invention is to provide a kind of active balance main span levels
The only Cable-stayed Bridge with Slanted Pylon structure and construction method of power, are not only simple in structure, and convenient and efficient.
In order to solve the above-mentioned technical problem, the technical scheme is that：A kind of active balance main span horizontal force it is only tiltedly
Pylon cable-stayed bridge structure, including earth anchor case, dorsal funciculus, leaning tower, abutment, pile foundation, main rope, girder and auxiliary pier, the main beam supporting in
Between abutment and auxiliary pier, the leaning tower is set on abutment, and connection is drawn in leaning tower front through main rope and girder are outstanding, and the leaning tower back side is through the back of the body
Rope is connected with outstanding draw of earth anchor case, and the pile foundation is made of the taper pile set on abutment bottom with straight stake.
Preferably, the earth anchor case is embedded in the soil body, the soil body and earth anchor case either flush.
Preferably, the dorsal funciculus both ends are anchored in respectively in earth anchor case and leaning tower, the both ends of the main rope respectively with leaning tower
It is connected with girder.
Preferably, the leaning tower tilts 18 ° -24 ° to end bay.
Preferably, the pile foundation and abutment are embedded in the soil body, the taper pile axis in the pile foundation and vertical line angle
It is 20 °.
Preferably, the abutment is consolidated with leaning tower, pile foundation and girder, the end of main beam and the auxiliary pier freely-supported.
Preferably, the taper pile is close to earth anchor case side, and straight stake is close to girder side.
Preferably, the taper pile and straight stake each along girder width direction it is uniformly distributed there are five.
A kind of construction method of only Cable-stayed Bridge with Slanted Pylon structure of active balance main span horizontal force, carries out according to the following steps：（1）
It is equipped with taper pile and each five of straight stake in the soil body, is constructed by the way of drill-pouring, pile foundation is poured with abutment consolidation, is carried out at the same time
