A series of laboratory tests by using a model excavator for the diaphragm wall method were carried out in order to investigate the interaction between the model excavator and the surrounding ground. The behaviour of the excavator was theoretically formulated and the theoretical values were compared with the experimental data. As a result, the calculated displacement of the excavator showed good accordance with the measured values for each ground condition investigated.
