| Abstract: | Based on the theoretical analysis,Xiangxi Autonomous Prefecture Aizhai continuous rigid frame bridge as engineering background,make use of bridge software BRanalysis to establish a construction control simulation model of the different closure＇s order,and analysis the impact of the different closure order on the bridge structure of the displacement and stress,to explore the general closure rules of the bridge,proposed the feasibility program of the closure and make related calculations for the closure program of the closure section,ensure the smooth closure of the bridge,and provide the corresponding reference for the analysis and construction of such bridges in the future. |
