Problems solved by technology

In reality, the construction of the track route often lags behind the bridge itself, and the river-crossing channel is idle for a long time after it is completed, reducing the efficiency of capital utilization

Abstract

The invention discloses a staged construction method of a multi-bridge-floor-layer suspension bridge for a highway and a rail. The suspension bridge is a three-bridge-floor-layer suspension bridge composed of a double-layer parallel main truss structure, rail transit is located on the uppermost layer, and highway traffic is located on the middle layer and the lower layer. The staged construction method of firstly constructing the highway traffic and then constructing the rail transit is adopted, construction on the rail transit can be carried out in the running process of the highway traffic, the scheme of the three-bridge-floor-layer suspension bridge is adopted, structural efficiency can be improved, the adaptive capacity of the structure on terrain is enhanced, the structure can adapt to the requirement for staged construction of the rail transit and the highway traffic, the recent engineering construction investment is effectively reduced, idle resources are avoided, meanwhile, the requirement that existing traffic circulation is not interrupted in the long-term construction period can be met, and the influence of construction on traffic is reduced to the largest extent.

Description

technical field [0001] The invention relates to the field of bridge construction, in particular to a staged implementation method of a multi-layer bridge deck public-rail dual-purpose suspension bridge. Background technique [0002] Urban rail transit usually adopts the way of combined rail and rail, and crosses rivers and valleys together with urban roads to save investment. In order to realize the rail transit crossing the river and meet the higher requirements for the passage of ships under the bridge, a long-span suspension bridge is often used to cross the river. At the same time, the way of co-construction of rails can make better use of scarce bridge resources and improve structural efficiency. However, due to structural force constraints and influences, the main cables and steel truss girders of the suspension bridge are usually completed in one go, and a channel for the track to cross the river is reserved. In reality, the construction of the track route often lag...
