Abstract: The geotechnical centrifugal model test was utilized to study the revetment design for the bank of river. Through this test, the working status of retaining wall was fpund during building-up period, usage period and suddenly reducing water-level period. These geotechnical questions, such as the changing law of earth-pressure and hydraulic pressure which act on the retaining wall-back, the settlement of foundation, the deformation and the whole stability of wall under different scheme and working mode, etc. were also analyzed. Synthesizing all all relevant factors, it is feasible to make the design scheme optimum and most economic.
