Ground-penetrating-radar-based active fault shallow ground surface spatial distribution detection method

Abstract

The invention relates to a ground-penetrating-radar-based active fault shallow ground surface spatial distribution detection method, and belongs to the field of geological survey. The method mainly comprises the following steps of primary election of an active fault passing region, ground-penetrating radar line layout and field data collection, ground-penetrating radar image processing and image anomaly region extraction and recognition and ground-penetrating radar image three-dimensional rebuilding and slice analysis. Accordingly, the detects that for an existing active fault shallow ground surface spatial structure detection method, the data collecting efficiency of a trial trench, an electrical prospecting apparatus, a magnetic susceptibility meter and the like is low, the resolution ratio is low, and the surface environment is destroyed are overcome, active fault detection under the complex environment can be achieved continuously in a large area, the method is easy to implement, the detection efficiency and precision are high, and the result is visual.

Description

[0001] technology neighborhood [0002] The invention relates to the technical field of geological survey, in particular to a ground-penetrating radar-based method for detecting the spatial distribution of active fault shallow surface layers. Background technique [0003] The area where the active fault zone passes is basically in the differential activity zone where the modern crustal movement is unstable, and it is easy to develop a variety of geological disasters, such as earthquakes, landslides, debris flows, etc., which will directly endanger people's lives and property, as well as the safety of urban construction and major projects. The fault occurrence process represents the process of an earthquake from seismogenesis to earthquake generation. The recorded seismic data in the world show that strong earthquakes above magnitude 7.0 basically occur on large-scale active fault zones. Research in this area is very important, not only can we fully understand the characteristi...
