Research on Cantilever Pouring Construction Technology in High-speed Railway Continuous Beam Engineering
Due to the characteristics of high speed,high requirements for precision of ballastless track system and large impact load,high-speed railway has strict requirements for the construction accuracy,mid-span creep deflection and post-construction settlement of bridge engineering.However,under the combined action of various complex conditions such as deep water,high altitude and cross-channel,the construction of cantilever pouring continuous beam is difficult.In order to ensure construction safety and efficiency,this paper studies the cantilever pouring construction technology of high-speed railway continuous beam based on engineering examples.According to the objective engineering situation,the special construction methods and technical points of beam construction in the environment with deep water and bare bedrock are emphatically analyzed.The linear monitoring and stress monitoring results of cantilever construction confirm the reliable effectiveness and value of construction technology,which can provide technical experience for the same type of engineering construction.
