Implementation method for multiple stress systems of beam bridge in straddle type monorail transport line

Abstract

The invention relates to an implementation method for multiple stress systems of a beam bridge in a straddle type monorail transport line, and belongs to the technical field of bridge engineering, wherein the implementation method is applied to all types of straddle type monorail transport including light-duty, medium-duty and heavy-duty straddle type monorail transport. According to the implementation method, an existing straddle type monorail transport line design is changed from a single simply supported system to the multiple stress systems including a simply supported variable continuous system, a simply supported variable continuous rigid frame system, a simply supported variable rigid frame system, a simply supported system and the like. Therefore, adaptability to the terrain, landforms, geological conditions, road conditions and the like on the line is enhanced, the smoothness of the line is enhanced, the number of expansion joints and supports on the monorail transport line is greatly reduced, abrasion of rubber tires and construction cost are lowered, the service life of a vehicle is prolonged, and operation and maintenance cost is lowered. The implementation method is a huge innovation in a true sense and has great significance in boosting the development of the straddle type monorail transport.

Description

technical field [0001] The invention relates to a method for realizing multiple stress systems of girder bridges in a straddle monorail traffic line, which is applied to the civil engineering of a straddle monorail traffic system, specifically to the stress of a girder bridge in a straddle monorail traffic line The system consists of simply supported variable continuous system, simply supported variable continuous rigid frame system, simply supported variable rigid frame system and part or all of simply supported system, and is applied to all straddle-type monorail traffic such as light, medium and heavy . Background technique [0002] Most of the girder bridge stress systems in any line of the existing straddle monorail transit system are composed of simply supported systems. Considering the expansion and contraction deformation of the track girder or turnout when the temperature changes or the foundation settlement, Expansion joints shall be provided at both ends of the t...

Problems solved by technology

[0007] The technical problem to be solved by the present invention is to change the design of the existing straddle-type monorail traffic line from a single simply supported system to a simply supported variable continuous system, a simply supported variable continuous rigid frame system, a simply supported variable rigid frame system and a simply supported variable rigid frame system. A variety of force-bearing systems combined together, such as a single-track system, enhances the adaptability to the terrain, landform, geology and road conditions of the line, enhances the smoothness of the line, greatly reduces the number of expansion joints and the number of supports on the monorail line, and reduces the Minimize the wear and tear on rubber tires and engineering cost, prolong the service life of vehicles and reduce operation and maintenance costs
