Model investigation on spudcan-sand interaction using transparent media

AbstractIn order to study the deformation mechanism of sand around the spudcan, the model test for spudcan-sand interaction was carried out by employing transparent media, which is also called "transparent soil". By means of the technology of Particle Image Velocimetry (PIV), the displacement vector field and contour map of sand around the spudcan were obtained. According to shallow strain path method (SSPM), the theoretical value of soil displacement around the spudcan was calculated. Compared with the experimental results, the correlation between the variation law of horizontal displacement of each group and the theoretical value reached 60%~80% in a certain range, which further verifies the rationality of the experimental method and theoretical analysis.
