标准摘要
[中文适用范围]： 本文件规定了实验室测试程序，以确定： a) 在不发生钢轨非弹性位移的情况下，可施加到钢轨上的最大纵向力，钢轨通过钢轨紧固组件固定在轨枕、承载物或无碴轨道元件上，或具有粘合剂紧固系统的嵌入式轨道样本在指定纵向位移下的纵向刚度，并且适用于任何类型的紧固； b) 轨道-桥梁相互作用计算所需的剪切位移和滑移数据。 [外文原描述]： This document specifies the laboratory test procedure to determine: a) the maximum longitudinal force that can be applied to a rail, secured to a sleeper, bearer or element of ballastless track by a rail fastening assembly, without non-elastic displacement of the rail occurring, or the longitudinal stiffness at a specified longitudinal displacement of a specimen of embedded rail with an adhesive fastening system, and for any type of fastening; b) the shear displacement and slip data required for track-bridge interaction calculations.
