Problems solved by technology

The inventor found that the detection results of the above-mentioned geophysical prospecting methods are mostly two-dimensional profiles, and the number of survey lines arranged on site is very large, so the formed two-dimensional profiles are very complicated, and the obtained single two-dimensional profile resistivity data can only reflect the information of one geological profile , it is difficult to reflect the actual situation of the complex underground structure, and it is also difficult to establish a model that can visually display the results, and the visibility is poor. When analyzing and explaining practical problems, it is often necessary to use the establishment of a 3D model

Abstract

The invention discloses a three-dimensional imaging method and system for ground surface comprehensive geophysical prospecting. The method comprises the following steps of: acquiring detection data ofa plurality of two-dimensional sections of a ground surface detection site; performing geophysical inversion on the detection data to form two-dimensional profile resistivity data; performing three-dimensional coordinate conversion on the two-dimensional profile resistivity data to obtain resistivity data of a three-dimensional coordinate system; and converting the resistivity data of the three-dimensional coordinate system into a three-dimensional model by utilizing a Kriging interpolation method.

Description

technical field [0001] The invention belongs to the technical field of geophysical prospecting, and in particular relates to a three-dimensional imaging method and system for surface comprehensive geophysical prospecting. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] In today's geophysical prospecting field, when conducting surface exploration, such as cross-hole method, well-ground method, high-density electrical method or comprehensive geophysical prospecting method, etc., are relatively common detection methods in engineering sites. The inventor found that the detection results of the above-mentioned geophysical prospecting methods are mostly two-dimensional profiles, and the number of survey lines arranged on site is very large, so the formed two-dimensional profiles are very complicated, and the obtained single two-dimensional profile resist...
