Finite Element Analysis Of Link-hanging Basket Of Single Tower Cable-stayed Bridge

With the development of the bridge research theory and the demand of practicalengineering，design and construction technology of long-span Bridges in our countryhave entered into a new stage. At present our country has built a large number oflong-span Bridges, including large-span cable-stayed bridge. As the key equipment oflarge span bridge cantilever construction, hanging basket was at constant developmentand innovation; Today the requirement of new type of hanging basket is higher thantraditional hanging basket, asking its convenient operation more flexible mobilelight-duty stability good safety performance is high and small deformation.This paper first reviews the development and status quo of cable-stayed bridge athome and abroad and its construction method, expounds the new guy hanging basket,the principles and characteristics of hanging basket. Then, to guo river bridge-the waterdroplets sections mixed combination single tower cable-stayed bridge as theengineering background, Using finite element program MIDAS/CIVIL,guo river threebridge whole bridge finite element model is established, Analysing the influence of thehanging basket’s size of the weight bridge construction stage on mechanicalcharacteristics，Self-respect than detailed comparative analysis on different hangingbasket (hanging basket weight with the standard weight ratio) beams under suspensionpouring bridge structure in different construction stages of the change of the stress anddisplacement of structure；Then, set up the engineering background of guy hangingbasket of finite element model, and the hanging basket analysis of the main structurecomponents are calculated；Finally, with the influence of weight of hanging basket ofmain girder of the bridge and the calculation results of hanging basket of maincomponents for the principle，our engineering guy hanging basket of main bodystructures were optimized, The more reasonable to determine the final size of the vortexthree river bridge construction hanging basket, provide reference for the smoothconstruction of the bridge. The research results show that the analysis results to thevortex three river bridge site construction monitoring and control work has certain help,at the same time can also be used for the same type bridge design and construction toprovide the related reference.
