Abstract：
As for the Nanchang Honggu immersed tunnel—the largest domestic immersed tunnel, a full-scale mod? el for the sand-filling of the foundation is designed, an equipment system and sand-filling monitoring system are established. Through sand-filling model tests for four cases, the real-time expansion process of the sand deposit, the law of pressure variation at the bottom of the model, the whole construction effect and the relative density of the sand deposit after sand filling are obtained. The feasibility and rationality of the construction technology design for the sand-filling method are verified.
