位移是评价公路高边坡安全的重要指标,目前卫星定位技术的测量精度最高能够达到毫米级,采样频率能够达到20Hz,而且实时解算数据,并能够适应复杂恶劣的工作环境。本文总结了目前卫星定位技术在公路边坡运营期变形监测中的应用情况,开发了适用于边坡监测的一机多天线技术,结合福银高速公路南平段,完成了基于卫星定位的边坡位移监测系统的研发与应用。
Displacement is an important index to evaluate the safety of high side slope of highway. At present, the highest accuracy of satellite positioning technology can reach millimeter level, the sampling frequency can reach 20Hz, and the data can be solved in real time and can adapt to the complicated and harsh working environment. This paper summarizes the current application of satellite positioning technology in deformation monitoring of highway slope during operation period and develops a multi-antenna technology suitable for slope monitoring. Combined with the Nanping section of Fuyin Expressway, the slope based on satellite positioning is completed Development and Application of Displacement Monitoring System.
