“…Modern medical ultrasound diagnostic technology has been improved and extended applications (Choudhary, et al, 2019, Mandrone, 2016, Poelma, 2017. The new ultrasound scanning imager with good real-time performance, strong penetration and high resolution has been well applied in hydrogeology and engineering investigation (Crapper, et al, 2000, Xiao, et al, 2015, Zou, et al, 2018, which has preliminarily solved the imaging measurement and diagnostic analysis of the suspended sediment concentration (Zou, et al, 2016), underwater topography (Zou, et al, 2015) and ow eld in the river engineering physical model (Ma, et al, 2018) by ultrasonic scanning techniques (Zou, et al, 2014). Therefore, it is of practical urgency and theoretical necessity to use the advanced medical diagnosis technology for reference and apply it to the visual monitoring and analysis of the weak structure area.…”

Aiming at the weak interlayer, potential structural plane or abnormal area that may have some risks in geotechnical engineering, a method of monitoring abnormal structure and evaluating potential geological hazards in geotechnical engineering based on phased array ultrasonic scanning imaging technique was proposed. The real-time ultrasonic video images of the internal structure of rock and soil mass at various positions and different angles in the target area, and the ultrasonic imaging profile of the processed internal abnormal structure can be obtained. The binarization features of abnormal structures in the images were statistically analyzed. The total number of non-zero pixels, non-zero discontinuous light spots and stripe bands is obtained. The ratio of the boundary length of all light spots and stripe bands to the number of pixels occupied by all light spots and stripe bands was obtained. Based on this, the criterion of the degree of potential geological hazards is established, and the visual monitoring of the internal abnormal structure of rock and soil mass and the accurate evaluation of potential geological hazards are realized. Based on the refined diagnosis and analysis of local abnormal areas, this method solves the problems that the existing techniques cannot realize the visual monitoring of the internal fine structure of rock and soil mass and carry out the refined analysis and evaluation of the potential geological hazards. This paper provides a new approach for the stability and safety analysis of geotechnical engineering or slope engineering.

Moving particles and the topographic bed under muddy water or in sediment-laden flow are often clouded by suspended sediments, making it hard to detect or analyze for visualization. This paper concerns applications of ultrasound imaging measurement method for the visual measurement of related water-sand parameters during sediment transport process in hydraulic model experiments. We use a B-mode ultrasound imaging system to measure the related parameters of suspended sediment concentration (SSC), underwater topographic riverbed, flow velocity and sediment incipient motion, conducted at a water channel. A comprehensive measuring system for the visualization of multiple water-sand parameters is established. Results show that the measurement and analysis of SSC and its space distribution, topography bedform, flow velocity and flow field, and sediment incipient velocity can be realized. Ultrasound imaging measurements of SSC and their space distribution can be shown in real time, and also dynamic monitoring and analysis of sediment incipient motion and topography bedform during the sediment transport process. This method realizes the experimental visualization of the topographic bed and sediment-laden flow. Application of an ultrasound imaging measurement system has promoted the development of sediment movement law research and related hydraulic model experiment measurement technique.
