超重载轨道过渡段力学性能分析
The research on characteristics of transition section in overloaded railway
摘要
Abstract
With the increase of the axle load of heavy railway, more stringent requirements are required for the rail foundation in the transition section. This paper was based on the subprojects of Hunan Zhexi Hydropower Station dam slide track reconstruction project, and the study on overload (axle load of 45 tons) track transition stress condition was conducted. On the basis of theoretical analysis, numerical simulation was used to analyze. In the new design of composite structure of rubber-bridge steel plate, the thickness of rubber 30mm, its elastic modulus 20 MPa is appropriate. The treatment measures proposed in this paper have certain practical value, and can be directly applied to the transition section of actual heavy haul railway engineering to alleviate the impact between wheel and rail.关键词
