Embodiment Construction
[0028] One embodiment of the present invention is the apparent resistivity profile ( figure 2 ) to automatically determine the position of the embankment cavity.
[0029] see figure 2 , the method for automatically determining the position of the cavity detected by the high-density electrical method is characterized in that the high-density electrical method exploration data is used to obtain the high-density electrical method apparent resistivity section diagram and the apparent resistivity index bar information displaying the apparent resistivity , extract the gray level information of the index bar corresponding to the apparent resistivity of the dam cavity, find out whether it matches the gray level information of the index bar of the apparent resistivity of the dam cavity, judge whether there is a hole in the dam and determine the position of the hole; the operation steps are as follows:
[0030] (1) Read the measured data of the high-density electrical method, obtain ...

The invention relates to an automatic confirmation method for probing a cavity position in a dam by a high density electrical method. The method comprising the following steps: using the acquired high density electrical prospecting data to obtain high density electrical method apparent resistivity section and apparent resistivity index strip information displaying the apparent resistivity, extracting the apparent resistivity index strip gray information corresponding to the dam cavity apparent resistivity to find out whether the area matched with the dam cavity apparent resistivity index strip gray information exists; and judging whether cavities exist in the dam and confirming the position of the cavities. The invention can overcome the defects of time consumption and influence of human factors by the manual judgment at present, and can automatically confirm whether cavities exist in the dam and the position information thereof fast and simply.
Description
technical field [0001] The invention relates to a method for automatically determining the position of a cavity detected by a high-density electrical method. The method is completely different from the current method in that the method uses the apparent resistivity section diagram obtained from the measured data of the high-density electrical method and the visual resistivity display. The resistivity index bar information is used to automatically determine whether there is a cavity and its position in a dam, and belongs to the technical field of intelligent information processing. Background technique [0002] With the rapid development of the national economy, the management of dams as the main barrier against floods and storm surges has attracted more and more attention. There are many reasons for the geological disasters of embankments, such as slope slides, landslides, subsidence of goafs, foundation cracks, broken zones, karst caves, seawater washouts under embankments,...
