Problems solved by technology

However, because the structure of variable-width bridges is very complex, and the existing computer-aided design software cannot meet the needs of automatic design, designers usually need to spend 5 times the time of designing and drawing compared with ordinary bridges, and each design is often Can only be used for bridges of one specification, poor versatility
Therefore, the design of variable-width bridges is a very troublesome thing for designers. The workload of designers is very large, and the cost is relatively high for general design units, and there is no such bridge at home and abroad. automatic design technology

Embodiment Construction

[0025] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0026] The automatic design method of the concrete variable width viaduct comprises the following steps:

[0027] 1) Determine the cantilever line

[0028] 1) Draw the road structure sidelines L1, L2 and road centerline L3 in the computer-aided drafting system according to the design parameters;

[0029] 2) Judging structure sideline L1, L2 from layer, road centerline L3, according to road structure sideline, the starting point of road centerline, the direction of end point judgment line, in the present embodiment, the linear direction of road structure sideline, road centerline determines From left to right, if it is judged that the direction of the line shape is from right to left, the position of the starting point should be changed, and the line shape should be changed from left to right;

[0030] 3) Determine the start beam Ci and end ...

Abstract

The invention discloses an automatic design method of a concrete broadening girder bridge. The method comprises the steps of confirming a cantilever line, confirming the position of a middle beam, confirming the number of chambers, confirming the position of a central line of a web plate, forming a structural map of a top plate, and the like. By adoption of the method, the automatic design of the concrete broadening girder bridge can be realized. A design scheme can be formed as long as a designer inputs conventional parameters. Workload of the designer can be effectively reduced, working efficiency is improved, and design cost of a design unit can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of bridge design, in particular to an automatic design method proposed for concrete variable-width bridges. Background technique [0002] With the development of the economy and the increase of urban car ownership, urban elevated roads and subways have become a better way to solve urban traffic congestion. In the selection of bridge forms for urban viaducts and overpasses, prestressed concrete continuous box girder structures are basically adopted, and variable-width bridges account for a large proportion of such concrete continuous box girder structures. However, because the structure of variable-width bridges is very complex, and the existing computer-aided design software cannot meet the needs of automatic design, designers usually need to spend 5 times the time of designing and drawing compared with ordinary bridges, and each design is often It can only be used for bridges of one specification, so the v...
