Abstract

Among monitoring for safety management of rockfill dams, measurements of exterior deformation is one of the most important measuring items. Exterior deformation of an rockfill dam is generally measured by surveying the quantity of displacement in the horizontal and vertical directions. However, by using the above method, rapidly responding after an earthquake or in other emergencies is difficult. The global positioning system (GPS) is a system that can perform surveys quickly at relatively low cost. In this research, we applied GPS automatic displacement measurement system for monitoring of exterior deformation of rockfill dams, and this system is found to be effective based on the results applied at several rockfill dam sites.
