This article uses a model test and PFC2D discrete element simulation
for systematic research on the mechanism and behavior of soil arching around passive
piles in sand. In the model test, soil arching effects with different pile spacing was
studied. In the discrete element simulation, the influence of pile spacing on soil
arching was revealed at the meso-level. The model test indicates that pile spacing
influences soil arching effects significantly. Numerical analysis also shows that pile
spacing is the most significant factor on soil arching surrounding passive laterally
loaded piles. From this study, the meso-mechanism and behavior of soil arching are
discovered further.
