Abstract

The invention discloses an underground reservoir dam body damage detection method and electronic equipment. The method comprises a step of acquiring a ground penetrating radar signal of an undergroundreservoir dam body, a step of preprocessing the obtained ground penetrating radar signal and obtaining ground penetrating radar preprocessing data including a reflected wave and a diffracted wave, astep of separating the diffracted wave in the ground penetrating radar preprocessing data, a step of performing angle domain compensation on the separated diffracted wave to obtain a first ground penetrating radar diffracted wave image gather, a step of levelling a diffracted wave signal in the first ground penetrating radar diffracted wave image gather and obtaining an offset velocity model of the ground penetrating radar signal, and a step of performing angle domain compensation on the separated diffracted wave again by using the offset velocity model to obtain a final diffracted wave imagegather of final ground penetrating radar, superimposing along an angular dimension in the final diffracted wave image channel gather and obtaining a diffracted beam focusing imaging result. Accordingto the invention, the recognition ability and efficiency of a disease diffracted wave signal of the underground reservoir dam body are improved, and the diseases of underground reservoir safety hazardare timely warned.

Description

technical field [0001] The invention relates to the technical field related to underground reservoirs, in particular to a method for detecting damage to an underground reservoir dam body and electronic equipment. Background technique [0002] Ground-penetrating radar is an effective device developed in recent decades for the exploration of underground targets. It has broad application prospects in many fields such as highways, airports, water conservancy, mines and tunnels. In the aspect of artificial dam disease detection, ground penetrating radar technology has also carried out a lot of research. He Kaisheng et al. (2005) studied the leakage detection of reservoir dams with ground penetrating radar; Tian Feng et al. (2006) analyzed the seepage hidden dangers of reservoir earth-rock dams in Northwest China through the change of ground mine waveform characteristics and the continuity of waveform events; Jia Yongmei et al. ( 2012) used ground penetrating radar method to stud...
