Description
Technical field
The utility model is related to bridge construction technical field of structures, are tilted in particular to a kind of novel only pillar of curve oblique pull
Bridge tower.
Background technology
In Curved Stayed-cable Bridge design, especially in rotator construction Urban Bridge, bridge floor is wider, lower king-post strut is shorter, construction
It is the key boundary condition of Stayed Cable Bridge Deethanizer design that place is limited.Only pillar bridge tower because its good adaptability is widely used,
It is especially more adaptable in rotator construction Urban Bridge.For the only pillar bridge tower of the cable-stayed bridge of curve beam section, since girder is deposited
It is Spatial Cable face in transversely eccentered, suspension cable, inclined cable face forms angle along bridge with bridge tower to vertical plane, and girder load passes through
Suspension cable will produce direction across bridge horizontal component when being transferred to bridge tower, to make bridge tower bear larger moment-out-plane, and only column
Formula bridge tower direction across bridge bending stiffness is smaller, causes bridge tower tower top direction across bridge horizontal displacement and king-post lower part moment of flexure larger.To solve
This problem, the bridge tower of conventional formula need to increase the ability that bridge tower section enhances bridge tower bending resistance square with this when designing.Such as the patent No.
For the Chinese invention patent of entitled " a kind of novel railway curve Cable-stayed Bridge with Slanted Pylon " of " CN105821753A ", the patent describe
A kind of curve Cable-stayed Bridge with Slanted Pylon, bridge are curve bridge, and bridge tower is to tilt bridge tower, is vase-shaped Sarasota structure, curve bridge is worn
Bridge tower is crossed, is differed to the beam section length of both sides along bridge positioned at bridge tower, causes the distribution of bridge tower moment-in-plane asymmetric, bridge tower is along bridge
Tower wall stress state in both sides differs greatly forwards, backwards, therefore in order to make two lateral balances, the program set bridge tower to incline structure,
Bridge tower is deviated along bridge to the shorter side of beam section length.In order to solve the problems, such as that curve beam section causes bridge tower moment of flexure larger,
The program on vase-shaped bridge tower by being arranged the structure of anti-transverse bending moment, while the structure for also increasing bridge tower is (vase-shaped
This body structure of bridge tower is more huge).Although the program can be good at solving the problems, such as that moment of flexure is larger, increase bridge tower and increasing
Add bending resistance square structure that can increase bridge construction cost, bridge budget is caused significantly to rise, and increased bridge tower structure can also
Increase the difficulty of construction of bridge.It can be seen that the Curved Stayed-cable Bridge presence of the prior art can not solve safety and economy simultaneously
The problem of depositing.
