站台限界测量仪测量基准分析

Measurement Datum Analysis of Platform Gauge Measurement Instrument

为保障铁路运输安全,在测量站台限界时应保障量值准确。从定义、测量方法等角度,分析站台限界测量基准,阐述站台限界测量仪分类。经过试验验证指出,测量站台限界尺寸时,应以建筑限界定义为依据、以轨面及轨面中垂面为基准。若测量基准不正确,可能导致较大的测量误差,给列车运行及乘客安全带来隐患。

In order to ensure the safety of railway transportation,the measurement value should be accurate when measuring the platform gouge.Based on the definition and measurement method,this paper analyzes the measure⁃ment datum of platform gauge,classifies of measuring instrument of platform gauge.Through experimental verifica⁃tion,it raises that the measurement size of platform gauge should be based on the definition of structure gauge,as well as the rail surface and the vertical surface of it as the reference.If the measurement datum is not correct,it may lead to a big measurement error,and bring safety hazard to train operation and passengers.
