积木式工业测量系统在桥梁模型试验中的应用研究

Application of Industrial Surveying System of Building Blocks Type in Bridge Model Test

    摘要
  • 摘要: 提出了一种以电子经纬仪为角度传感器的积木式工业测量系统方法,推导了系统的测量精度,并将其应用于竖琴式斜拉桥模型试验变形测量中。研究结果表明,在6 m×5 m×4 m的空间区域内,此系统测量精度均优于±0.2 mm,与百分表测试值对比,其差值小于20%。

     

    Abstract: The merits and demerits of many kinds of deformation measurement methods are compared.The method of industrial surveying system which uses electronic theodolite as angle sensor is advanced.The principle of industrial surveying system is introduced.The measurement accuracy of the system is calculated and it is firstly applied to measure the deformation of the harp shaped cable-stayed bridge model.The study result shows that the measurement accuracy of the system is up to 0.2 mm in 6 m×5 m×4 m spatial region.The difference between industrial surveying system and dial gauge is within 20% percent.The proposed method is widely applied to the other civil engineering structural experiment and has broad prospects for application for its reliability and creditability.
