孔内超声波合成孔径成像与多频扫描探测系统
The detection system based on ultrasonic synthetic aperture imaging and multi-frequency scanning
摘要
Abstract
It is particularly important for the underground engineering design and construction in karst de-velopment areas to identify the refined structure of hollow areas and underground morphology based on the struc-tural characteristics of underground rock mass and survey techniques in deep voids.In order to further understand the"black box"structure of deep underground rock mass and master key technology of accurate exploration in underground space,this article introduces a detection system by borehole ultrasonic synthetic aperture imaging and multi-frequency scanning.According to the synergistic effect of optics and acoustics inside the borehole,this system derived a multi-frequency ultrasonic scanning technology suitable for detecting complex geological bore-hole rock mass,and designed a comprehensive survey equipment for borehole rock mass structure with intelligent perception and recognition capabilities.In addition,the system can synchronously survey borehole rock walls,caves inside the borehole,and near-field surrounding rocks in complex geological environments.Combined with its supporting analysis methods,we have constructed a comprehensive survey system for borehole rock mass structure integrating"observation,measurement,and characterization".The test results show that the ultrason-ic synthetic aperture imaging and multi-frequency scanning detection inside the borehole can perform 360°pre-cise detection by going into inaccessible underground spaces along the borehole,enriching the survey data of rock structure in underground space development and construction,which has forward-looking and wide application prospects.关键词
