Problems solved by technology

Since the technology at this stage mainly focuses on the detection of leakage in the middle of the dam body, it has great limitations in the detection of leakage in the dam foundation and abutment, and there is a certain error in the detection depth, and the amount of measurement data is relatively small. Therefore, the current It is difficult to accurately identify the location of hidden dangers of reservoir dam leakage with existing technology, which will further affect the safety and precise policy implementation of water conservancy management departments

Abstract

The invention provides an earth and rockfill dam time-domain electric field monitoring system and a precise imaging method, and belongs to the technical field of real-time monitoring of earth and rockfill dam leakage safety problems. The monitoring system comprises a communication cable, a drilling cable, a drilling electrode, an integrated electrical method host, a data acquisition and processingplatform and the like; earth and rockfill dam earth electricity information is transmitted to the input end of the communication cable through the drilling cable, then transmitted to the integrated electrical method host through the output end of the communication cable and finally transmitted to the data collecting and processing platform. The precise imaging method comprises data observation and data inversion imaging. According to the monitoring system, a transverse, longitudinal and time-direction three-direction dynamic observation layout is applied, a dam body multi-hole measuring linecombined observation method is combined, real-time accurate imaging of a geoelectric field can be achieved, complete coverage type monitoring of the earth and rockfill dam is facilitated, one-time arrangement is achieved, the service cycle is long, and mass data can be obtained compared with a traditional method; according to the observation system, the time shifting electrical method technology is applied to normalized monitoring of the earth and rockfill dam, and breakthrough of the monitoring and detection integrated technology can be achieved.

Description

technical field [0001] The invention relates to the technical field of real-time monitoring of leakage safety issues of earth-rock dams, in particular to an earth-rock dam time-domain electric field monitoring system and a precise imaging method. Background technique [0002] Before the 1980s, limited by the construction technology of reservoir dams, earth-rock dams formed by layered rolling and layer-by-layer thickening were often used in the construction process of a large number of small and mountain pond reservoirs. Due to the long time, the built earth-rock dams have a high probability of leakage, and a large number of earth-rock dam reservoirs have different degrees of hidden dangers of leakage, which will face serious security threats during the flood season. The leakage monitoring of reservoir dams in my country lacks normalization, and there are few real-time monitoring projects for reservoir dam leakage, and reservoir dams are often detected and monitored only when...
