Abstract
The invention relates to a mixed type cable-supported bridge. A main tower adopts a main tower form of a suspension bridge and a cable-stayed bridge; a main beam in a main midspan sling area adopts a steel box beam; a main beam in a stay cable area adopts a steel box beam, a steel-concrete combined beam or a concrete beam; and anchor spans at the two ends adopt pre-stress concrete main beams or other types of main beams. The main tower utilizes the main tower form of the suspension bridge or the cable-stayed bridge or the combination of the suspension bridge and the cable-stayed bridge according to needs of stress and landscape; a steel-concrete combined section is arranged between the steel box beam and the concrete beam; the steel box beam and the concrete beam are connected by steel strands, shear nails and the like to guarantee reliable and smooth force transmission; and the number of auxiliary piers in the edge span stay cable area can be changed according to the requirements of structural stress and rigidity. According to the mixed type cable-supported bridge, a self-anchored suspension bridge is combined with the cable-stayed bridge to take the advantages of the two types of bridges; the span of the formed bridge can reach 2500m; in addition, the mixed type bridge is large in spanning capability and does not need a large-scale concrete anchor, so that the bridge can be built in deep seas and other complicated environments; and the mixed type cable-supported bridge also can be applied to bridges with the span of hundreds of meters.
Description
Technical field
The present invention relates to a kind of hybrid cable load-bearing bridge.
Background technology
In recent years, along with the Chinese society rapid development of economy, bridge technology constantly strides forward to striding greatly with the deep-sea also in quick progress.The maximum span that suspension bridge has built up is 1991m, and the above span of 3000m constantly is suggested, even the span of 5000m also proposes; The maximum span that cable stayed bridge has built up is 1088m, and elongated river, the Shanghai that is about to build bridge span reaches 1092m, and is highway and railway bi-purpose cable-stayed bridge (4 line railways+6 track highways).
The earth anchored suspension bridge span ability is big, and span can be accomplished 3000～4000m, but huge anchorage need be built in two ends, is not suitable under the medium complicated environmental condition in the ocean of the depth of water, building; Self-anchored suspension bridge need not built huge anchorage, but span can not be very big, only accomplishing about 1000m, otherwise bad processing such as the pressurized of main push-towing rope anchorage zone, girder is stable, economy is also bad; Cable stayed bridge need not built huge anchorage yet, but that its span also can't reach earth anchored suspension bridge is so big, only accomplishing about 1500m, otherwise also uneconomical, unreasonable.
Summary of the invention
The objective of the invention is to above-mentioned present situation, it is strong to aim to provide a kind of span ability, need not build the hybrid cable load-bearing bridge of huge anchorage again.Span ability is strong, need not build huge anchorage again.
The implementation of the object of the invention does; A kind of hybrid cable load-bearing bridge; King-tower adopts the king-tower form of suspension bridge and cable stayed bridge; Main span span centre hoist cable district girder adopts steel case beam, and suspension cable district girder adopts steel case beam, steel-concrete bondbeam or concrete beam, and the two ends anchor span adopts the girder of prestressed concrete girder or other pattern.
The present invention combines traditional self-anchored suspension bridge and cable stayed bridge; Performance advantage separately forms a kind of novel mixed cable load-bearing bridge, and span can be accomplished about 2500m; Both span ability was strong; Need not build huge anchorage again, enrich the pattern of bridge, be adapted at building under the medium complicated environmental condition in deep-sea.Adopt bridge span of the present invention can accomplish about 2500m, can certainly adopt the bridge of hundreds of rice span.The quantity of end bay suspension cable district auxiliary pier can suitably increase and decrease according to needs such as structure stress, rigidity.
Span of the present invention is big, need not establish anchorage, is applicable under the medium complicated environmental condition in deep-sea to build, and can solve the insufficient rigidity problem of Longspan Bridge, has improved the wind resistance and the road-ability of Longspan Bridge.Save construction costs, the duration is short, convenient construction.

The specific embodiment
Below in conjunction with accompanying drawing the present invention is further specified.
With reference to Fig. 1, be main span L between the present invention's two king-towers 1, reach 2500m or hundreds of m; Be end bay L1, L2 between both sides king-tower and the anchor span girder 5, anchor span girder 5 places are anchor span L3, L4; Main span central authorities hoist cable district span is L5, reaches 1000m, and suspension cable district, main span both sides span is L6, L7, reaches 750m; The vertical distance of minimum point is main push-towing rope arrow degree H in main push-towing rope cat head IP point and the main span, H=(1/4～1/7) L.
Mark 1 among Fig. 1 is a king-tower, and 2 is main push-towing rope, and 3 is hoist cable district girder, and 4 is suspension cable district girder, and 5 is the anchor span girder, and 6 is suspension cable, and 7 is hoist cable.
King-tower 1 of the present invention can be according to needs such as structure stress, views, adopt the king-tower form of suspension bridge, cable stayed bridge, or the combining form of the king-tower of suspension bridge, cable stayed bridge.The king-tower of receiving frame tower in the step shown in Figure 2 adopts suspension bridge and cable stayed bridge king-tower 1-1 commonly used.The king-tower of succinct frame tower shown in Figure 3 adopts suspension bridge king-tower 1-2 commonly used.The king-tower of camber line H shape tower shown in Figure 4 adopts cable stayed bridge king-tower 1-3 commonly used, and king-tower 1-3 is twin columns.The king-tower of only post tower shown in Figure 5 adopts cable stayed bridge king-tower 1-4 commonly used, and king-tower 1-4 is only post.
Steel-mixed adapter section is set between steel case beam and the concrete beam, the two is combined, guarantee that power transmission is reliably smooth and easy through steel strand and WELDING STUDS etc.
Steel case beam girder adopts steel-concrete bondbeam 4-2 as shown in Figure 7, or adopts concrete beam 4-3 as shown in Figure 8.
Main span span centre hoist cable district girder 3 adopts steel case beam 4-1 form as shown in Figure 6 similar, and details such as thickness of slab are different, and two ends anchor span girder 5 can adopt the girder ballast of prestressed concrete girder or other pattern.Steel-mixed adapter section is set between steel case beam and the concrete beam, the two is organically combined through steel strand and WELDING STUDS, reliably smooth and easy to guarantee power transmission.
The quantity of end bay suspension cable district auxiliary pier can suitably increase and decrease according to needs such as structure stress, rigidity.
According to present case history; And combination relative theory analysis; The span of self-anchored suspension bridge can be accomplished about 1000m; The span of cable stayed bridge can accomplish about 1500m, and the span L of the present invention that therefore self-anchored suspension bridge and cable stayed bridge is combined can accomplish about 2500m, can certainly adopt the bridge of hundreds of rice span.
