Electrical observation system and method for dam dynamic monitoring

Abstract

The present invention discloses an electrical observation system and method for dam dynamic monitoring. The system comprises a remote data management platform, a field data management platform, an electrical monitoring data collector, an electrical power supply electrode, a measuring electrode and an electronic signal transmission wire. According to the method, the electrical monitoring data collector is utilized, the electrical power supply electrode, the measuring electrode and the electronic signal transmission wire arranged at the dam, a short straight line-shaped three-dimensional electrical method is adopted, and therefore, the electrical monitoring data of a dam can be dynamically monitored, the change rules of electrical monitoring data during different periods are analyzed, information related to the security of the dam can be extracted, and thus, the long-term dynamic monitoring of the security of the dam can be realized. Since the electrical monitoring data of the dam are dynamically obtained, the change conditions of the interior of the dam can be indirectly identified, and the nondestructive, long-term and dynamic safety monitoring of the dam can be realized. The electrical observation method has the advantages of high predictability and low monitoring costs.

Description

technical field [0001] The invention relates to an electrical method observation system and method for dynamic monitoring of dam safety, through long-term and regular dynamic monitoring of electric field changes of hydraulic structures such as dams, to find potential safety hazards caused by internal structure changes. Background technique [0002] At present, the safety monitoring of hydraulic structures such as dams is mainly realized by monitoring the changes of deformation, seepage, pressure, temperature, etc. of hydraulic structures such as dams. [0003] Using the above method to monitor the safety of the dam mainly obtains the changes of the dam through the sensors arranged around the dam or inside the dam, so as to realize the safety monitoring of the dam. If sensors are arranged around the dam to measure the change of the dam, it is necessary to monitor the safety hazard of the dam when the surface of the dam changes, and once the surface of the dam changes, very ob...

AI Technical Summary

Problems solved by technology

If sensors are arranged around the dam to measure the change of the dam, it is necessary to monitor the safety hazard of the dam when the surface of the dam changes, and once the surface of the dam changes, very obvious changes may have occurred inside the dam, and the danger of the dam is already high, which may lead to a very short time left for governance security risks, so the method is not very predictable

If the sensors used to measure the changes of the embankment are pre-embedded during the embankment construction, the stress structure of the embankment may be changed due to the addition of the sensor, and once the sensor fails, the monitoring cannot be carried out

If it is necessary to install sensors inside the dam for the already constructed dam, it is necessary to perform destructive operations such as drilling on the dam, causing structural damage to the dam
