摘要
无缝道岔是发展超长无缝线路的关键技术，而道岔区导轨、基本轨纵向力分布和位移的计算则是无缝道岔设计的先决条件。本文提出固定辙叉单开道岔和可动心轨单开道岔钢轨纵向力及位移计算的力学模型，编制了实用计算程序，并对６０ｋｇ／ｍ轨１２号单开道岔进行分析。
To develop the welded switches is a key technology for the construction of the continuously welded rail track.In the paper,mechanical models are advanced for calculating the rail longitudinal forces and displacements of the split switch turnouts with rigid frogs and with movable frogs.A computer program is designed.As an examples,the rail longitudinal forces and displacements of the Chinese No.12 switch turnouts are given out.
