Construction Safety Inspection Platform of High-speed Railway Super Large Swivel Bridge Based on Numerical Simulation
In recent years,when constructing bridges across existing railways,in order to reduce interference with railway operation lines during the construction process,parallel railways are often used to pour bridges and then rotate them.This article combines the example of the Zhaochuan super large swivel bridge project on the Beijing Zhangjiakou high-speed railway to monitor the key and difficult points of the swivel bridge during construction,and compares and analyzes it with computer simulation data to obtain the mechanical performance parameters of the swivel bridge,including static friction coefficient(μs),dynamic friction coefficient(μk),and friction couple distance.Model each part of the bridge body and establish a safety monitoring and early warning system,warning platform,and storage medium.In this platform,different colors such as red,orange,yellow,and green are used to visually distinguish and display bridge structures at different construction periods and locations during the construction process,establishing a complete bridge construction safety monitoring platform.
