Abstract

This paper presented a particle size effect on model retaining wall by comparing the experimental and finite element analysis. The experiments were conducted with air-dried Toyoura sand and Soma sand plane strain condition, both sand are standard sand in Japan. The wall was oved horizontally into sand. The hights of sand mass in these experiments were 5 cm, 10 cm, and 15 cm. The finite element analysis employed a constitutive model in which non-associated strain hardening-softening elasto-plastic materila was employed. This analysis introducted the effect of shear band thickness. The result obtained from the finite element analysis showed a good agrement with the results obtained from the experimental investigation. From both experimental and analytical results, there was evident of particle size effect due to shear banding.

Abstract

Anchors have been used for many years as restraint structures to maintain the stability of slopes. As the restraining effect of such slopes is exerted by the tensile force acting on the involved anchors, investigation of this tensile force is important when maintaining anchors. As multiple anchors are installed on slopes, investigation of numerous anchors is essential to determine the tensile force. This study describes the maintenance of anchors based on the residual-load results obtained using the involved SAAM (Sustainable Asset Anchor Maintenance) system, which uses a compact and lightweight SAAM jack capable of performing lift-off tests on numerous anchors.
