Description
Technical field
The present invention relates to highway and urban road bridges technology, more particularly, to a kind of ultra-high performance concrete waveform steel abdomen
The construction method of plate combination box beam bridge.
Background technology
The Concrete Thick web of conventional concrete box beam is replaced using Wavelike steel webplate, box girder with corrugated steel webs is formed, no
Only structure is moulded attractive in appearance, while the problem of conventional concrete box girder web cracking is avoided, excellent in durability, therefore big
It is widely applied in middle span bridge.
Compared with traditional concrete box girder, because the torsional rigidity and anti-distortion rigidity of box girder with corrugated steel webs section have
Reduced, so the width of box girder with corrugated steel webs should not be too wide.In general, the cast-in-place box beam or ripple of single box single chamber
Shape steel web plate composite box girder Breadth Maximum is less than 5m, and broader single case box beam will form single box double room by increasing web quantity
Or single-box multi-cell section, or apply lateral prestressing tendon, to adapt to the requirement of bridge width, it is to avoid floorings stress is excessive,
So result in and the increase of beam body weight occur, difficulty of construction increase, concrete is difficult the problems such as pouring into a mould.
UHPC（Ultra High Performance Concrete, ultra-high performance concrete）It is a kind of high intensity（Tension
Intensity is more than 150MPa more than 7MPa, compression strength）, high-durability New Style Concrete Materials.The high performance feature masters of UHPC
It is the hardening of stress and stretching strain, that is, produces the behavior similar to the surrender of steel tension, the UHPC mechanics of appropriate arrangement of reinforcement
The close steel construction of performance.In current level, show for the advantage in this major design engineering of such as bridge, made
Obtain overall structure outward appearance and tend to light and handy, amount of reinforcement is reduced, some engineerings even eliminate reinforcing bar.
Using UHPC materials, bridge member can reduce physical dimension, tend to very thin frivolous, so as to reduce deadweight, improve knot
The efficiency of structure opposing load and the span ability of increase bridge, while lifting, setting up convenient.Therefore, by traditional Wavelike steel webplate
Box beam and ultra-high performance concrete（UHPC）With reference to, prestressing force ultra-high performance concrete Wavelike steel webplate continuous box girder is formed, it is right
Solve existing prestressed concrete continuous box girder bridge cracking in webs and deadweight is larger, the difficult problem such as construction complexity is significant.
The content of the invention
