| Pedestrian suspension bridge has beautiful shape, simple structure, clear forceand reasonable economy, bridge construction process is not affected bytopography,channel and other conditions.The design theory of suspension bridge ismore mature, there are many calculation software which has sufficient accuracy innonlinear analysis and dynamic analysis. At the same time,although many suspensionbridge were builted in our country,the specific specifications and manuals ofsuspension bridge construction and monitoring were not compiled, especially forpedestrian suspension bridges,due to the lack of experience in construction andrelated specification, some pedestrian suspension bridges can not reach the intendeddesign target,or even may cause accidents.This paper rely on a pedestrian suspension bridge,under the premise of fullyunderstanding the design intent,analyze its construction and focus on the difficulties.In this process, access to a large number of domestic and foreign literature, finiteelement analysis is used to obtain expected reasonable construction monitoringdata.The main contents of the construction monitoring are: pedestrian suspensionbridge tower construction and monitoring, main beam construction andmonitoring,cable clip and sling construction and monitoring,alignment monitoring ofmain cable and main beam etc., analysis the cable shape monitoring results,decklinear monitoring results and sling cable tension monitoring results.Comparedtheoretical results with site monitoring results,estimate construction errors andfeedback on the actual construction,take a full range of process control on the bridgein the construction process,make the construction safe and ensure the designspecifications meet the design expectations. This paper focuses on the key anddifficult of construction and monitoring process in this pedestrian suspensionbridge,the research results may provide construction and monitoring references forsimilar pedestrian suspension bridges. |
