Based on the systematic engineering concept,we put forward for the first time the theory of Building Information Modeling (BIM) plus to guide the ship lock construction.Integrating BIM and 3-D printing,hydraulic simulation and internet,we carry out the planning,design,construction and operation management of the ship lock project and thus realize a new mode for constructing the ship lock based on BIM plus.The engineering practices prove that this new mode is simple with high efficiency,and solves the construction difficulties of complex ship lock structure easily.Therefore this mode has a vast application prospect and may serve as the theoretical guide and technical reference for similar projects.
