Description
Technical field
It is used for civil engineering bridge technology field the present invention relates to one kind, is more particularly to a kind of hybrid structure of arch and beam formula concrete
Continuous bridge structure, realizes and a kind of possesses bigger span ability and the more preferably new continuous bridge girder construction shape of economy
Formula.
Background technology
During bridge is highway, railway, urban road and road and water conservancy construction, in order to across various obstacles (such as river
Stream or other structures) works.Divided by structure feature, bridge can be divided into beam, arch, rigid frame, hang and combined system.
Concrete structure mainly uses beam, arch, rigid frame system.Concrete continuous girder bridge is a kind of basic bridge type of Longspan Bridge, with
Unlike continuous rigid frame bridge pier consolidation, superstructure of continuous beam bridge is connected with bridge pier using fixed or movable bearing, therefore
Compared with continuous rigid frame bridge, pier shaft height is smaller, although reduce span ability, but bearing capacity is greatly improved, and is
China or even the world are in a kind of most widely used long span concrete bridge structure of field of traffic.
The Technological Economy of traditional construction with brackets prestressed concrete continuous beam is applicable across footpath about in 20~60m, hangs
The Technological Economy of arm method construction large span prestressed concrete continuous bridge is applicable across footpath about in 80~150m, exceedes in across footpath
During 150m, easily there are the defects such as middle span deflexion, beam body deformation, cracking, had a strong impact on the service life and durability of bridge, limited
The span ability of this bridge type is made.At present, the large-span concrete continuous bridge that China has nearly hundred occurs in that said structure
Property defect and endurance issues.On the whole, the main deficiency of traditional prestressed concrete continuous beam is：(1) structure is held
Carry efficiency low, when across footpath is more than 150m, easy cracking, downwarp problem, technical risk increase, the security and durability of structure
Deterioration, the impatient acute deterioration of engineering economy；(2) superstructure causes bridge pier, foundation engineering scale big from great.
So under this background, develop and a kind of completely possess bigger span ability and more preferably economy, newly continuous
Girder construction form, has great practical value.
The content of the invention
The purpose of the present invention is to be to provide a kind of hybrid structure of arch and beam formula concrete continuous girder bridge structure type, from structural system
