Sensuron technology was recently utilized to measure the settling movement related to a metro boring project in Beijing, China. A 2D sensor was placed in a reduced scale boring test setup to measure the soil displacement resulting from a simulated excavation process. The existing methods of Digital Image Correlation (DIC) and electronic-based displacement sensors, due to their inherent limitations, were unable to produce the desired measurements within the test volume. The fiber-based 2D shape sensor acquired an accurate soil displacement distribution along a continuous line of the surrounding soil and provided sub-millimeter validation of their settling models.
