Method and system for rapid investigation of slurry dispersion range based on magnetic tracer material

Abstract

The application belongs to the field of tunnel and underground engineering grouting technology, and provides a slurry diffusion range rapid exploration method and system based on magnetic tracer material, and the technical scheme is: based on the determined magnetic field detection line, drawing the target area grouting before and after the magnetic field distribution map; according to the target area grouting before and after the magnetic field distribution map, the abnormal magnetic field distribution characteristics are calculated; based on the obtained magnetic grouting body magnetization rate and magnetic field response characteristics after grouting, the underground magnetic grouting body distribution range is inverted, and the magnetic grouting body stratum model is drawn; the magnetic grouting body stratum model is modified combined with the obtained abnormal magnetic field distribution characteristics, and the magnetic grouting body distribution range is obtained. By adding magnetic tracer material in the slurry, combined with the airborne magnetic survey method, the slurry diffusion range rapid exploration in the stratum grouting reconstruction engineering is realized, and the efficiency of the grouting effect evaluation is improved.
