Description
Technical field
The present invention relates to bridge technology, relate in particular to a kind of combined box beam bridge spanning the sea and construction method thereof.
Background technology
The majority that the non-navigable of present bridge spanning the sea adopts is prestressed concrete box girder, steel-mixed compound beam and steel case beam scheme.As Construction of Hangzhou Bay Cross-sea Bridge offshore approach span adopts 70m prestressed concrete continuous beam scheme, Coastal Area access bridge adopts 50m prestressed concrete continuous beam scheme; The marine non-navigable in Transbay Bridge, Qingdao adopts 60m prestressed concrete continuous beam scheme; Donghai Bridge adopts 70m prestressed concrete continuous beam scheme; Zhuhai and Macao bridge non-navigable in port adopts 120m steel purlin composite continuous beam bridge and the continuous steel of 85m-mixed compound beam scheme.And these schemes all exist problems.
Prestressed concrete box-beam bridge is a kind of bridge construction form being most widely used at present.But engineering practice for a long time and application present situation reflect that prestressed concrete box-beam bridge exists a lot of inferior positions.First, dead load has accounted for the more than 80% of total internal force to the internal force of controlling cross section generation, larger across footpath, this ratio is also just larger, even likely reach 90% left and right, this has restricted the span ability of bridge greatly, is subject to the restriction of offshore lifting ability simultaneously, lifting tonnage is unsuitable excessive, and therefore prestressed concrete box-beam bridge is generally not too large across footpath.The problem of bringing is like this: basic quantity increases, and then causes, set a roof beam in place often, the set a roof beam in place series of problems such as long in time limit large to water currents; Simultaneously due to the little feature of conventional concrete tensile strength, in order to strengthen as much as possible across footpath, the mode of increasing section size and panel thickness that conventionally adopts Large Span Bridges improves its rigidity of section to meet structure stress requirement, this has not only increased the deadweight of case beam and construction costs, has also increased difficulty of construction simultaneously; In addition, concrete web is due to stressed complexity and construct some reasons in processing, construction, all can there is diagonal crack in major part, this diagonal crack not only can cause the reduction of bridge construction Rigidity and strength, also can accelerate the corrosion of reinforcing bar, the reinforcing bar of corrosion can cause the expansion of volume, thereby make concrete cracking, particularly under this weakly alkaline environment in ocean, to further destroy concrete stress performance, reduce the durability of material and the supporting capacity of structure, have influence on the attractive in appearance and application life of bridge.
If bridge spanning the sea adopts steel work or steel-mixed combining structure, it can have increase by a relatively large margin compared with prestressed concrete continuous beam bridge really across footpath, but seawater is alkalescent, steel and concrete structure are had to stronger corrosiveness, steel are in the poor durability of marine environment, and later maintenance expense is high.And high containing steel structure bridge cost, if the non-navigable of bridge spanning the sea adopts steel work bridge type, its economy is by poor.
At present, there are some large-span concrete box girder bridges to adopt main spans middle part to adopt the modes such as Performance of High-Performance Lightweight Aggregate Concretes (as the main span Norway Manfred Stohl Ma Qiao that is 301m) and main span middle part employing steel case beam (as the main span New Chongqing Shibanpo Yangtze River Bridge that is 330m) to improve its span ability, also there are the methods such as the web vertical of employing presstressed reinforcing steel to reduce box beam risk, although these methods have certain effect, but these schematic designs and work progress are comparatively complicated, the problem of box beam does not obtain essence solution yet simultaneously.
In addition, the domestic bridge type that also has scholar to propose to be referred to as prestressing force ultrahigh-performance concrete continuous box girder bridge, the main feature of this bridge type is that full-bridge all adopts ultra-high performance concrete material, but this kind of bridge type also exists problems.First, this bridge type is crossed and thinly can not be arranged rope in too much body due to panel thickness, and therefore external prestressing tendon is more, and because external tendon is exposed to poor durability in air, the maintenance problem of bringing thus and later stage drag-line are changed problem, expense is all larger; And because full-bridge adopts ultra-high performance concrete, all plates are sheet-type structure, the deadweight of whole bridge reduces significantly compared with ordinary concrete box girder bridge, bring thus under Vehicle Load girder stress amplitude excessive, the fatigue problem of bringing is thus worth going into seriously, permanent stressed unfavorable to girder; Because girder adopts sheet-type structure, bending resistance and the torsional rigidity in its cross section are less, and torsion and the distortion effect that therefore more diaphragm must be set resist girder, also can bring thus external prestressing layout and turn to difficult problem; In addition, because plate is crossed the stretch-draw place local stress problem that transfinites in thin brought prestressed stretch-draw process and is also merited attention.
Summary of the invention
The technical problem to be solved in the present invention is to overcome the deficiencies in the prior art, provide a kind of simple in structure, endurance quality good, be applicable to greatly across footpath, the combined box beam bridge spanning the sea that has a extensive future, and technological process is simple, easy construction, fast, combined box beam bridge spanning the sea construction method rapidly.
