Application of CCD micro-deformation monitoring technology to slope remote monitoring

探索低成本、高精度长期定点监测技术是目前边坡监测工程中急需解决的问题。CCD微变形监测仪通过光电信号的相互转化来获取边坡的稳定性信息,比起传统的监测仪器,其在精度、时效性及成本上均具有一定的优势,通过远程无线遥控监测,节省监测人力物力。在分析CCD微变形监测系统工作原理的基础上,将其应用于诸永高速公路K101边坡的长期监测,与前期安装的GPS、全站仪共同工作一段时间后,对比相近观测点的监测值,结果显示,CCD微变形监测系统所取得的数据具有良好的精度和长期稳定性,表明该监测系统监测效果良好,适宜于边坡的长期监测使用。

At present, the most critical question in monitoring slope engineering is to find a new technology which can be suited for long-term and fixed-point situation, and it needs a lower-cost, higher precision and longer distance. Charge coupled device （CCD） is the technology which can get the information about slope stability by the mutual transformation of photoelectric signals. Compared with the traditional monitoring instruments, CCD has some advantages in accuracy, timeliness and cost. Meanwhile, it could achieve remote wireless control. So it significantly saves manpower and resources that required to monitoring. Based on exploring the working principle of the CCD micro-deformation monitoring system, it has been applied to the K101 slope of Zhuji-Yongjia expressway for a long-term monitoring; after a period time of work with GPS and total station together, it is shown that the data by CCD is favorable in precision and stability; and it is also demonstrated that the CCD micro-deformation monitoring system is suited for long-term monitoring of slope for a good effect.
