Kyowa Earthquake Dam Embankment Behavior Observation Device
Made in Japan
Manufacturer: Kyowa Electronic Instruments Co., Ltd.
Model: Earthquake Dam Embankment Behavior Observation Device
Understanding the seismic behavior of dams, which are super-large civil engineering structures, is important information for the structural design of dams. The results of earthquake analysis obtained from the completed dam are compared with design calculations and reflected in subsequent dam designs. At the seismic observation point, the vibration waveform during the earthquake is recorded for the vibration of the upper part of the dam body, the bottom (foundation ground) and the ground for the three components (X, Y, Z).
