Abstract

The invention belongs to the technical field of bridge engineering and provides a bridge design method for a cable stayed-arch bridge system. The method comprises the following steps: confirming a rise span ratio of an arch rib as 1/5-1/3 and the quantity of stay cables in the vertical surface of the bridge as 12 according to the span, width and load requirements of the arch bridge; dividing a girder into seven equal sections along the span direction and selecting six suspension points on the girder; simultaneously, dividing the arch rib into eight equal sections along the horizontal direction and selecting seven suspension points on the arch rib; arranging the stay cables according to the shape in the drawing 1 and modeling a finite element; performing loading combination computing according to the permanent action, variable action and accident action in the design specifications; lastly, confirming the construction of each part of the bridge. Few stay cables are adopted for replacing the densely arrayed suspension rods, so that the aesthetic effect of the bridge is promoted; the mechanical property of the cable stayed-arch bridge system is better than that of a vertical suspension rod system, a net arch system and a Nielsen system; the appearance effect is better than that of the net arch system; compared with the single appearance of the Nielsen system, the appearance of the cable stayed-arch bridge system is more variable.

Description

A kind of Bridge Design method of oblique pull-arch bridge system
Technical field
The invention belongs to technical field of bridge engineering, is related to bridge, a kind of oblique pull-arch is related specifically to The Bridge Design method of pontic system.
Background technology
In existing arch bridge, suspension rod generally using vertically arrangement form at equal intervals, even if in the introversion of arch rib top or In the arch bridge of flare, from from facade, most of suspension rods are also adopted by vertically arrangement form at equal intervals.Nielsen style arch bridge hangs Bar adopts uniform oblique suspension rod, and net donor system is then using more densely covered netted oblique suspension rod.
Engineering practice shows that Nielsen style arch bridge amount of deflection when by live loading is significantly less than vertical suspension rod arrangement and is encircleed Bridge.But Nielsen style arch bridge is geometrically being evenly arranged to full-bridge suspension rod, and suspension rod quantity is more, is not suitable for suspension rod The design of special aesthetic requirement is disposed with, and its stress performance is not optimal；The suspension rod more crypto set of net donor system, Although stress performance is slightly better than Nielsen style arch bridge, suspension rod is too many, affects the aesthetic of bridge.
The content of the invention
The invention provides a kind of Bridge Design method of dilute Suo Fei uniform oblique pull-arch bridge system, it is adaptable to 300 meters Arch bridge in across footpath, with good mechanical property and changeful appearance.
Technical scheme：
A kind of Bridge Design method of oblique pull-arch bridge system, step are as follows：
(1) across footpath according to arch bridge, width and load requirement, determine that the ratio of rise to span of arch rib is 1/5～1/3 and bridge is vertical In face, the quantity of suspension cable is 12；
(2) by girder along 7 decile of across footpath direction, 6 suspension centres are chosen on girder：A points, B points, C points, D points, E points and F Point, while by arch rib 8 decile in the horizontal direction, 7 suspension centres are chosen on arch rib：1. point, 2. point, 3. point, 4. point, 5. point, 6. Point and 7. point；
(3) suspension cable arrangement is as follows：First skew cables are 1. point-A points, and the second skew cables are 2. point-A points, 3rd skew cables are 2. point-B points, and the 4th skew cables are 2. point-D points, and the 5th skew cables are 3. point-C points, and the six roots of sensation is oblique Drag-line is 4. point-B points, and the 7th skew cables are 4. point-E points, and the 8th skew cables are 5. point-D points, and the 9th skew cables are for 6. Point-C points, the tenth skew cables are 6. point-E points, and the 11st skew cables are 6. point-F points, and the 12nd skew cables are 7. point-F Point.
The invention has the advantages that：The suspension rod for replacing gathering using a small amount of suspension cable, improves the aesthetic effect of bridge； Mechanical property is better than vertical suspension rod system, net donor system and Nielsen style；Appearance compares Nelson also superior to net donor system The single profile of system is more full of variety.
Description of the drawings
Fig. 1 is oblique pull-arch bridge system bridge elevation.
In figure：1 arch rib；2 girders；3 suspension cables；
1., 2., 3., 4., 5., 6., suspension centre 7. for suspension cable on arch rib；
A, B, C, D, E, F are the suspension centre of suspension cable on girder.
Specific embodiment
The specific embodiment of the present invention is described in detail below in conjunction with technical scheme and accompanying drawing.
Embodiment
A kind of Bridge Design method of oblique pull-arch bridge system, step are as follows：
(1) across footpath of arch bridge be 100 meters, it is wide 9 meters, lateral arrangement is：1 meter of footpath+driveway, 6 meters of+1 meter of footpath, The ratio of rise to span of determination arch rib first is 1/5；
(2) 12 skew cables are chosen；
(3) by girder along 7 decile of across footpath direction, 6 suspension centres (A, B, C, D, E, F) are chosen on girder, while by arch rib 8 decile, chooses 7 suspension centres (1., 2., 3., 4., 5., 6., 7.) on arch rib, sees accompanying drawing 1 in the horizontal direction；
(4) suspension cable is arranged according to the shape of accompanying drawing 1, suspension cable arrangement is as follows：First skew cables are 1. point-A points, the second skew cables are 2. point-A points, and the 3rd skew cables are 2. point-B points, and the 4th skew cables are 2. point-D Point, the 5th skew cables are 3. point-C points, and six roots of sensation suspension cable is 4. point-B points, and the 7th skew cables are 4. point-E points, the 8th Skew cables are 5. point-D points, and the 9th skew cables are 6. point-C points, and the tenth skew cables are 6. point-E points, the tenth oblique pull Rope is 6. point-F points, and the 12nd skew cables are 7. point-F points, and set up FEM (finite element) model；
(5) Load Combination calculating is carried out according to the permanent action of design specification, variable action, accidental action etc., it is final true Determine each several part construction of bridge.
