Figure 9.
The experimental arrangement shows two cameras positioned above a soil container at an angle of 56 degrees to monitor the response of a buried structure. Measurement points are labelled A 1 through A 5, B 1 through B 5, C 1 through C 4, D 1 through D 4, and E 1 through E 4 across the soil face. Additional labels identify positions S 3 and S 4 near the structure and Box A, Box B, Box C, and Box D along the side boundary. Horizontal spacing of 93 millimetres is indicated between adjacent sensor columns, while vertical spacing values of 25 millimetres and 75 millimetres define the measurement grid. The layout illustrates the camera configuration and spatial distribution of monitoring points used for displacement tracking.Schematic overview of the instrumentation, which includes sixteen accelerometers within the soil, four mounted on the laminar container, one on the table, and two on the structure, accompanied by two high-speed cameras for digital image correlation (DIC) measurements
