| Abstract;This study evaluated the uplift resistance of anchor on two-layered sand masses, by comparing a conventional 1g model test with finite element analysis. In the experiment, a sand bed was prepared by pluviating air-dried Toyoura sand. The tests were performed six kinds of sand masses that were uniform dense, uniform medium, uniform loose, lower layer of dense(upper layer of medium and loose) and lower layer of medium(upper layer of dense) conditions. The height of sand mass was 20cm for uniformed condition and 10cm for each upper and lower-layers in two-layered sand mass. From the study, the results of finite element analysis showed good agreement with experimental results in all cases. In the uniform condition, the softening after reaching peak load and the shear band propagation differed according to the density of sand mass. In two-layered sand masses, the shear band propagation was depended on the density regardless of the position of layers. The softening after reaching peak load was remarkable on lower layer of dense condition and not clear on lower layer of medium condition. The load-displacement curves were affected the density of lower layer and not sensitive on density of upper layer. (author abst.) |
