The advantages, disadvantages and risk control points of the double-layer Bailey beam construction scheme without intermediate piers are summarized and analyzed, and the applicable construction conditions of the construction scheme are proposed, which can be used for reference in the selection of construction schemes with similar engineering conditions.展开更多

Combining with main arch construction monitoring program of No. 2 bridge in north district of Changbai international tourism resort,main content and key technologies are recommended. Considering the various influential factors during the construction process,linear adjustment is handled to ensure that the stress and linear of main arch meet design requirements.展开更多
