Having similar place, they are, by cable-stayed bridge and suspension rod, main push-towing rope, girder load is transferred to bridge tower respectively, therefore cable-stayed bridge,
The bridge tower of suspension bridge is the most sturdy, and rigidity is the biggest.It is relatively big, especially that bigger rigidity causes bridge tower to respond under geological process
It is when bridge span is relatively big or bridge is positioned at Near-source earthquake district, and bridge tower anti-seismic performance is often difficult to meet design requirement, knot
Structure design difficulty is bigger.
Design usually requires that cable-stayed bridge, suspension bridge girder under normal operating condition along along bridge to slidably, bridge tower
Need to retrain with direction across bridge at bridge pier, common supporting system is as described below: girder is at bridge tower, at the bottom of beam and bridge tower thwart beam
Between arrange along bridge to single-directional sliding support and bidirectional sliding support, additionally arrange between beam side and pinner side along bridge to list
Use as wind-resistant support to sliding support；Girder is at auxiliary pier and shared Dun Chu, then in arranging at the bottom of beam and between pier top along bridge
To single-directional sliding support and bidirectional sliding support；As earthquake resistant construction, along suitable bridge to installing viscous between girder and bridge tower thwart beam
Liquid condenser.Above-mentioned supporting system can meet the design requirement under normal operating condition of cable-stayed bridge, suspension bridge, also can be real
Now along bridge to Aseismatic Design, but not for direction across bridge and the earthquake resistant construction of vertical seismic action.
Common cable-stayed bridge, Suspension bridge structure supporting system can realize along bridge to Aseismatic Design, but direction across bridge and vertically
Shake does not has rational glissando, is only capable of using Traditional method of seismic design method to be designed.When using Traditional method of seismic design method,
Owing to bridge tower is for maintaining the importance of structural system, geological process usually requires that holding elastic stage, therefore generally
Supporting system in, bridge tower self-strength can only be relied on to resist direction across bridge and Vertical Earthquake Loads, lack the structure that reasonably consumes energy,
Design can only use increase bridge tower sectional dimension, arrangement of reinforcement, basis scale means to meet requirement, auxiliary pier and shared pier are also
There is same problems, substantial amounts of waste of material, the increase of construction cost and difficulty of construction thus can be caused to strengthen.Especially work as bridge
When location is positioned at Near-source earthquake district, near-field earthquake not only earthquake intensity is high, and vertical seismic element is very big, uses tradition anti-
Shake method for designing is often difficult to meet design requirement, and design difficulty is the biggest.

Above-mentioned two-way vibration absorption and isolation support is different according to position, is labeled by sequence number, is respectively labeled as first to the 3rd
Two-way vibration absorption and isolation support (A1 to A3), three above-mentioned seat structures are identical, specification size difference.
Above-mentioned vertical vibration absorption and isolation support is different according to position, is labeled by sequence number, is respectively labeled as the first to the second
Two seat structures that vertically vibration absorption and isolation support (B1 to B2) is above-mentioned are identical, specification size difference.
Under normal service condition, the disk spring assembly of bearing at bridge tower, auxiliary pier and shared pier, the first c-type mild steel I and
The motion of the second c-type mild steel II of bearing bottom is pinned by the shear pin of its correspondence respectively, girder only can along along bridge to slip, and
At bridge tower, auxiliary pier and shared pier, girder direction across bridge is the most restrained, meets static design requirement.
Under geological process, bearing disk spring assembly, bottom the second c-type mild steel II at bridge tower, auxiliary pier and shared pier
Shear pin all cut off, disk spring parts can occur vertical deformation and drive first c-type mild steel I occur plastic elongation, pressure
Direction across bridge can be occurred between in the middle part of compression deformation, base plate and bearing to slide, drive the second c-type mild steel II at base plate to occur plasticity to draw
Stretch, compression.Now, the plastic deformation of the second c-type mild steel II of bearing A1 at the bottom of direction across bridge seismic energy passes through beam at bridge tower
The disk spring of seat A2 collateral with beam and the plastic deformation of the first c-type mild steel I dissipate；At bridge tower, vertical seismic action energy then leads to
The disk spring of bearing A1, B1 at the bottom of lintel and the plastic deformation of the first c-type mild steel I and the second c-type mild steel II of beam collateral seat A2
Plastic deformation dissipate.At auxiliary pier and shared pier, direction across bridge seismic energy passes through the second of two-way vibration absorption and isolation support A3 base plate
C-type mild steel II occurs plastic elongation, compression to dissipate；Vertical seismic action energy then passes through two-way vibration absorption and isolation support A3 with vertical
The disk spring assembly of vibration absorption and isolation support (Bidirectional slide) B2 and the first c-type mild steel I occur plastic deformation to dissipate.It addition, it is whole
The suitable bridge of body structure is then dissipated by the viscous liquid antivibrator C at the bottom of beam and between crossbeam to seismic energy.
Compared with common supporting system, after using the supporting system of the present invention, not only cable-stayed bridge, Suspension bridge structure normally make
Require to be satisfied with the static design of state, also achieve Structures under Earthquake three-dimensional seismic isolation design (along bridge to, horizontal
Bridge is to vertical).Estimated, after using the supporting system of the present invention, the seismic response of bridge tower, auxiliary pier and shared pier can reduce
20% 30%, thus, in ensureing structural earthquake on the premise of safety, make bridge tower, auxiliary pier, share pier and basic engineering more
Add rationally, saved construction cost and reduced design difficulty and difficulty of construction.
The two-way vibration absorption and isolation support used in this supporting system and vertical vibration absorption and isolation support be difference under normal operating condition
Possess suitable bridge to slide and Bidirectional slide function, possess respectively in geological process direction across bridge, vertically subtract shock insulation and vertically subtract every
Shake function, other use has the supporting system that similar functions bearing is constituted, and two-way vibration absorption and isolation support is used for beam body side
Face realizes direction across bridge and vertically subtracts the design of shock insulation, is this patent same principle, should be protected.
Embodiment described above is only to be described the preferred embodiment of the present invention, the not model to the present invention
Enclose and be defined, on the premise of designing spirit without departing from the present invention, the relevant technical staff in the field's various changes to the present invention
Shape and improvement, all should expand in protection domain as determined by claims of the present invention.
