ABSTRACT
In this study, a centrifuge modelling technique has been developed, in which the loading process can be simulated from design conditions to the ultimate failure conditions on an embedded wall in soft rock. A series of centrifuge tests has been carried out to investigate the influence of embedment depth on the stability of self-standing steel pipe sheet pile walls. Observed results reveal that with relatively small embedment, the wall can stand in the design condition with a reasonable safety margin against ultimate failure. The stiff sheet pile walls suffer by rigid body rotation about a pivot point and small increment in the embedment depth e.g., 0.5m, can significantly increase the wall stability.
