Description
Technical field
The present invention relates to a kind of bridge, particularly a kind of bridge with arch-type structure system and girder structure system.
Background technology
In bridge construction, generally be divided into girder structure system, arch-type structure system bridge.In recent years, built the co-operative system of cable stayed bridge and continuous rigid frame bridge, as Sichuan Panzhihua bridge and Croatia's bridge, this structural system makes full use of orographic condition, selected the girder structure system to cooperate mutually, make it to have bigger span ability and reduce construction costs to a certain extent with respect to traditional girder structure system, arch-type structure system bridge, but this is the cooperation between beam type force structure system, the binding site of girder structure and arch-type structure body needs to be supported by bridge pier, further increases span ability and has been subjected to restriction.
In the arch bridge evolution, there are upper, middle and lower to hold the formula arch bridge, material has steel bridge and concrete bridge, has also built up steel-concrete combined structure bridge in recent years.In the bridge of these structures, encircle and be main bearing member, bridge deck and spandrel column (or suspension rod) they are Force transmission parts, the main arch circle is generally rectangle, box-shaped or truss etc.Its weak point is that the main arch circle should be born bigger axle power, also has big moment of flexure in arch springing, vault, 1/4L arch section simultaneously, arch springing sectional dimension height, and material usage is many, and abut thrust is big.Ability is big though single hole jumps, and is equilibrium level thrust, the combination end bay stride the footpath washability little, the landform adaptive capacity is poor.
Summary of the invention
Technical problem to be solved by this invention provides a kind of have arch-type structure system and girder structure system bridge, and the application of this structural system bridge can increase span ability and further reduce engineering and cause valency.
The technical solution adopted for the present invention to solve the technical problems is: bridge of the present invention comprises main span that is made of the arch-type structure system and the end bay that is made of the girder structure system, it is characterized in that: described arch-type structure system and girder structure system are vertically docked between main span bridge pier and the end bay bridge pier along bridge floor.
After taking abovementioned technology, because docking with the girder structure system, the arch-type structure system forms the combination construction system, the bridge force-bearing performance improves, and can reduce the support bridge pier under the binding site in the former system, therefore can improve the span of end bay and reduce construction costs.
As to further improvement in the technical proposal, for further improving the main span span and reducing construction costs, described arch-type structure system comprises main arch rib, subarch rib, limit arch rib and tie-rod case, the two end supports of main arch rib is on two main span bridge piers, the limit arch rib is connected with the support end of main arch rib and extends to the both sides end bay, the two ends of subarch rib then are connected with main arch rib, limit arch rib respectively, and the tie-rod case is connected with main arch rib, subarch rib, limit arch rib by connecting elements.
Main arch rib, subarch rib and limit arch rib constitute combined type arch-type structure system, main arch rib pressurized, subarch rib tension, and power transmission is clear and definite, has reduced the internal force of steel tie-rod simultaneously, has also improved end bay rigidity, therefore can further improve the main span span and reduces construction costs.
The invention has the beneficial effects as follows, the arch-type structure system is docked with the girder structure system and is formed the combination construction system, main arch rib, subarch rib and limit arch rib constitute combined type arch-type structure system, the bridge force-bearing performance improves, power transmission is clear and definite, reduced the internal force of steel tie-rod simultaneously, also improved end bay rigidity, therefore can improve bridge span and reduce construction costs.
