摘　　要：本文针对桥梁施工监测过程中无法在桥面测量底板高程的问题,设计了一种可引申的高程测量标志。该标志采用了伸缩折叠结构,适用于不同底板厚度且方便携带,从桥面测量底板高程,极大地提高了测量效率。In view of the problem that the floor elevation cannot be measured on the bridge deck in the process of bridge construction monitoring,an extensible elevation measurement mark is designed.The sign adopts the structure of expansion and folding,which is suitable for different floor thickness and convenient to carry.It can measure the floor elevation from the bridge deck and greatly improve the measurement efficiency.

关 键 词：桥梁监测 高程测量 测量标志 底板高程
