Abstract: In this paper the observation accuracy of horizontal displacement by manual to the gate of Shuikou Hydropower Station has been analyzed and the observation method has been also discussed, which indicate the defects by manual observation. It is proved to be the most favorable scheme to optimize the monitoring system for large hydraulic structures deformation using automatic observation.?
