利用GPS监测高大建筑物动态位移法研究

应用GPS卫星导航定位系统对高大建筑物动态变形进行监测已成为可能。本文介绍了利用GPS进行建筑物动态监测的原理、方法，详细阐述了用该法对深圳地王大厦在台风作用下测试结构物的位移和振动频率的方法。用该方法测定了物体在强台风作用下动态位移，量程可达几百毫米，量测精度为±5mm，可测定0．1～10Hz的振动频率。测试结果表明GPS可以作为大型建筑物动态变形的一种测量方法。

Big Building Displacement Monitoring with GPS

This paper introduces the theory and method of GPS in application to building displacement mornitoring. This method was tested to measure the dynamic displacement and vibration frequency for Diwang Building in Shenzhen city while it was attacked by typhoon. The result of that reaches to accuracy of 5mm, vibration frequency of 0. 1-10 Hz, that makes GPS possible in dynamic displacement measuring for building structure of big size.
