  • In order to better guide the design,laying and maintenance of welded turnouts,the effects of stress-free temperature difference between two railway lines on the rail displacement and temperature force of a welded turnout were investigated.In addition,the influences of the link style of turnouts,the number of turnout,the style of turnout frog and the ballast resistance of road bed on the rail displacement and temperature force were analyzed.The results show that stress-free temperature difference between a welded turnout and an adjacent line or a turnout will lead a big longitudinal force and a great displacement of the welded turnout.
