Abstract: Disclosed is a real-scale landslide simulator for earthquake reproduction comprising: a base; a tower provided in one end of the base; a multi-stage simulation soil box provided movably in the vertical direction along the tower and filled with soil, which is subjected to compaction; a movable bogie provided movably in the horizontal direction on the upper surface of the base while supporting the other side of the multi-stage simulation soil box; a vertical reciprocator that reciprocates the multi-stage simulation soil box in the vertical direction; and a horizontal reciprocator that reciprocates the movable bogie in the horizontal direction. It is possible to reproduce liquefaction and shear strength reduction caused by an earthquake and analyze a real-scale landslide mechanism caused by an earthquake by repeatedly providing vertical and horizontal vibrations to the soil and forming a groundwater level using the groundwater simulation device.

Abstract: A system for management of a circuit breaker counter according to an exemplary embodiment of the present invention includes a data processing unit receiving state change data and measurement data of at least one of a circuit breaker and a current measuring unit and transferring an event on the basis of the state change data and measurement data; and a counter managing unit counting a total operation, a load-breaking operation and a fault-breaking operation of the circuit breaker, based on the event and the measurement data, and outputting and storing respective count accumulation values.
