| Abstract: | The dam monitoring system of Sanbanxi Hydropower Station has been in normal operation for 13 years.The method of manual geometric leveling is mainly used to evaluate the deformation extent and the running status of the dam in order to ensure the dam operation safety.By analyze the settlement process line,the settlement distribution map and the settlement regression fitting curve,the relationship between the annual settlement and water level of the reservoir is found.The measurement data still show the uneven settlement occurs between the main dam sections and there is a positive correlation between year's settlement and the reservoir water level.Especially,monthly settlement dramatically increased when the water lever is over 460 meters. |
