Abstract

In order to study the characteristics and evolution process of soil arching effect behind a circular pile, an experimental study on pile-soil interaction based on the transparent soil technology was carried out from a microscopic perspective. Firstly, the tests as to transparent soil ratio were carried out to obtain the soil with desirable physical and mechanical properties. Secondly, the experimental system was designed and the speckle field image of the interaction between the transparent soil and pile was obtained. Finally, the displacement vector diagram was obtained through particle image velocimetry (PIV) technique, and the displacement variation rule of the transparent soil was further analyzed. The results show that the movement trend and displacement characteristics of soil particles under the action of the circular pile can be obtained through displacement vector, and the arch structure formed by displacement contour, namely, the soil arch structure behind the pile, can be further interpreted, as it presents a parabolic shape and its range is related to pile diameter, pile spacing and depth. The larger the pile diameter is, the larger the soil arch area is. When the pile diameter is 30 mm, the soil arch is up to 100 mm. Meanwhile, the pile-soil interaction affects larger region. The larger the pile spacing is, the larger the maximum arch height is. When the pile spacing is 80 mm, the soil arch height also reaches 100 mm. The soil arch height under different depths shows a similar trend. The deeper the depth is, the smaller the maximum arch height is. When the depth is 50 mm, the arch height is 60 mm. According to the fitting formula, the maximum arch height decreases gradually from the pile top to the bottom along the pile, and at the same time, it increases at first and then tends to stabilize with the increase of soil displacement. The stable value is correlated positively with pile diameter and pile spacing and negatively with depth.
