Abstract In the full-scale model test of sand-flow method,time-history curves of sand-deposit radius,water pressure in the sand-flow system and the one under the model board are obtained under the conditions of different bottom surface materials of immersed tunnel. The analyses show that quadratic relationship exists between sand-deposit expansion trend in each direction and time under different bottom surface materials. Sand-deposit expands faster and has a better balance and fullness under the smooth material condition,with the maximum radius of 879 cm and the fullness of 99.3%,which is slightly higher than the one under the rough condition. It is feasible to increase the designed radius of sand-deposit to simplify construction. Material conditions and sand-deposit expansion do not have an effect on the water pressure of system except the one under the model board.
