Walls of piles have often been used as a stabilizing device for landslides. In this study, a series of laboratory model tests have been carried out to help elucidate the preventive mechanism of these piles. Namely, a pile or group piles were installed in a sandy model ground made by piling aluminum rods up on a bottom plate. The load acting on each pile and the ground movement around the piles were then measured while or after moving the bottom plate downward uniformly. The main results obtained from these model tests are as follows: 1) A kind of arching action takes place in the ground surrounding the piles, and 2) Zigzag arrangement piles are more effective than Parallel piles since a so-called double arch can be anticipated with the Zigzag piles.
