Abstract: A study on the centrifuge model test for the stability of gravity concrete block wharf wall has been carried out. Two schemes are compared for revealing the stability differences between two super-deep gravity concrete block quay with top sizes of 9.5 m(scheme 1) and 8.5 m(scheme 2), respectively. The results show that the horizontal displacement is 42 mm and 82 mm, the ground subsidence is 110 mm and 222 mm, as well as the pore pressure is 320 kPa in the groundsill, respectively. It is confirmed that centrifuge model test for wharf wall stability is effective. The value of horizontal displacement and ground subsidence of scheme 2 is larger than the scheme 1, which is out of permission of criterion, and the disbennifit to the stability of project is obviously due to the excess pore pressure disappeared slowly. The conclusion is that the scheme 1 with top size of 9.5 m is preferable.

Key words: horizontal displacement, ground subsidence, pore pressure, stability
