ABSTRACT
A series of unreinforced and reinforced soil slope model tests were conducted on a representative problematic soil (Kanto Loam). In this paper, the centrifugal loading test results observed at the ultimate failure-state are presented. The primary objective of these tests were to identify the effectiveness and applicability of anchor plate attached soil nailing method in the stabilization of natural and cut slopes especially made of the problematic soils which losses friction as the water content increases. The centrifuge model tests illustrated that the anchor plates are not only effective in increasing the safety factor, but also in reducing the settlement. Therefore, the proposed method exhibits wide applicability. Further studies are recommended to investigate the applicability and limitations of the method in varying drainage conditions.
