The application of IBIS-L remote monitoring system for micro deformation of terrain in dam safety monitoring

摘要

IBIS-L is an advanced remote monitoring system based on microwave interferometer, which integrates the interferometric survey, stepped frequency- continuous wave and synthetic aperture radar. IBIS-L can do high precise, large range, Omni-directional, real-time and remote displacement monitoring. The system can be widely applied in the monitoring of small-displacement changes in the dam, mountain, slope, surface, buildings and bridges. The monitoring technology can get the displacement changes of every part, analyze the deformation mechanism and characteristics and forecast the disaster of dangerous region timely. So it can provide a reliable basis for disaster prevention, greatly reducing or avoiding the loss on people's life and property. We introduce the external deformation monitoring process and outcome of IBIS-L in a hydropower station dam and provide a useful reference for the application of IBIS-L to the similar dam.
