Abstract:

t 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.

Key words: charge coupled device (CCD), slope engineering, remote monitoring
