Investigation on the effects of wall slenderness on failure behavior of DCM wall using a simplified small-scale physical model test

This paper presents behavior of DCM walls up to failure state, described by small scale experimental results. Ground spring model is adopted in the setting up of the physical model to solve the problem of down scaling. DCM walls with various slenderness at a certain volume have been experimented to illustrate the shape effects on the behaviors, especially in the failure state. Effects of wall shape on wall failure modes, i.e., wall structural failure and external soil failure have been captured, which are in accordance with the potential failure related to wall-to-excavation shape factor in our previous study.
