Abstract

This paper presents the results of small scale model tests on the behavior of propped wall and ground movements during deep excavation. Small scale model tests were performed in order to investigate the effects of various influencing factors on the deep excavation, such as stiffness of ground and unsupported span length. The results of model tests indicated that the wall behavior is significantly influenced not only by the stiffness of ground but by the over-excavation, and that the wall behavior can be reduced by decreasing the unsupported span length and increasing the stiffness of ground.
