Earthquakes, strong winds, floods, rainstorms or landslides are the main natural hazards for important buildings such as dams.It may cause huge damage to the building, so grasping the response characteristics of the building under the action of earthquake and strong wind is an important basis for evaluating the damage of the building and improving the vibration resistance of the building, so as to develop the ground motion monitoring is necessary for the health and safety of buildings.
The dam strong vibration monitoring system is a reliable, sturdy and comprehensive monitoring system. It can monitor the damage to the dam foundation caused by buildings in severe environments such as earthquakes, strong winds, floods, and landslides in real time, and enables emergency response to possible catastrophic events.
Dam strong vibration safety monitoring refers to on-site inspections and observations made on the construction and operation of reservoir dams and observations made with instruments and equipment. It usually includes two stages of data collection and data analysis. Its purpose is to establish the ground motion attenuation relationship and determine the response spectrum through strong vibration monitoring data. The seismic design of the engineering structure is more reasonable and reliable to ensure the safe operation of the dam.

There are many hidden dangers that affect the safety of the dam. It is caused by the design, construction and management of the dam. Through the efforts of the designers, construction personnel and operation management personnel is possible, but it is not caused by natural earthquakes or reservoir-induced earthquakes. Seismic motion has an important impact on the stability of the dam body, dam foundation and spillway. The shape of the dam during the earthquake is very complicated. Therefore, monitoring the seismic response of the dam is an important part of dam safety monitoring. For example, in the development of water elevators in the Lancang River Basin in Yunnan Province, the development of the water elevators in the upper reaches of the Yellow River in Qinghai, and the development of the water elevators in the Wujiang River in Guizhou, once the upstream dam is affected by the earthquake, will it cause potential safety hazards to the downstream dam and take action on itself? What kind of safety precautions need to provide a scientific basis based on the analysis results of seismic observation data.
G01NET-3 high-precision data recorder (strong seismic instrument), QZ2013 force balance acceleration sensor and G01NET engineering ground motion and vibration provided by our company
The monitoring system software can compose a dam strong vibration safety monitoring system. Monitoring data can be transmitted to the monitoring center through optical cables, bridges, etc.
The monitoring center server installs G01NET project ground motion and vibration monitoring system software to analyze the data online in real time.
When a strong vibration event occurs, the monitoring software can automatically issue a professional analysis report according to the “Specifications for the Safety Monitoring of Hydraulic Structure Strong Vibration” (SL 486-2011);
The results of the report can be sent to management personnel via SMS and email.
