Longitudinal V-shaped cable bent tower cable-stayed bridge

A longitudinal and cable-tower technology, which is applied to cable-stayed bridges, bridges, bridge parts, etc., can solve the problems of increasing the size of bridge pylon transverse girders, creating a sense of bulkiness, and wasting space on the bridge deck, so as to achieve good landscape and take into account the bridge Function and landscape requirements, enriching the effect of facade modeling

Problems solved by technology

When the bridge deck is wide, in order to avoid intrusion into the traffic clearance of the motorway, sufficient width should be reserved under the inclined tower column, resulting in waste of bridge deck space
The vertical tower columns will increase the size of the bridge tower beams, resulting in bulkiness and waste of materials

Embodiment 1

[0028] In this embodiment, the attached figure 1 with 2 Shown is a longitudinal V-pylon cable-stayed bridge.

[0029] Specific structure:

[0030] The cable tower is a V-shaped structure, along the longitudinal direction of the bridge, it is composed of inclined tower columns at a certain angle. The inclined tower columns are the main span side tower column 1 and the side span side tower column 2; The side span side tower columns 2 are connected above the bridge deck by inter-pylon cable 3, the main span side tower column 1 lifts the main span of the main girder through the main span stay cable 4, and the side span side tower columns 2 pass through the side span Stay cable 5 lifts the side span of main girder. The present embodiment adopts the scheme that the bridge deck is connected as a whole.

[0031] The angle between the main span side tower column 1 and the side span side tower column 2 is 85 degrees. The side tower column 1 of the main span is 40 meters long and ha...

Abstract

The invention provides a longitudinal V-shaped cable bent tower cable-stayed bridge. The bridge is characterized in that a cable bent tower of the cable-stayed bridge is of a V-shaped structure, namely a structural form that two inclined tower columns form a certain included angle; the inclined tower columns are connected through inhaul cables, and meanwhile the main span and the side span of themain beam are hoisted by the two tower columns through the inhaul cables respectively. Landscape modeling of the inclined tower column is combined with a reasonable stress system to form a brand-new cable-stayed bridge structure. Rich facade shapes are generated while traffic clearance of a traffic lane is not affected, and bridge functions and landscape requirements are both considered.

Description

technical field [0001] The invention relates to the technical field of bridge structure design, in particular to a longitudinal V-shaped cable-tower cable-stayed bridge. [0002] technical background [0003] A cable-stayed bridge is a cable load-bearing system composed of three basic components: towers, beams, and cables. It is a bridge in which stiffening beams are mainly under compression, cable towers are mainly under compression and stay cables are under tension. Therefore, the three elements of a cable-stayed bridge are cable towers, stiffening beams constituting the deck system, and inclined cables. One end of the inclined cables is anchored to support the stiffening beams, and the other end is anchored to the cable towers. [0004] As a very creative bridge type, the cable-stayed bridge has repeatedly defeated the traditional bridge type in bridge design competitions due to its advantages of convenient cantilever construction, economy, and variety, and has become the...
