Aiming at the key issues such as the comparison and selection of the digging port layout plan and the optimization of traffic layout in the graphic design of an inland port,the sediment and traffic digital simulation and BIM technology are used for modeling,calculation and analysis,and the siltation and plane traffic organization of different schemes are obtained.The plane transportation organization situation provides scientific methods,reliable data support and visualization means for the comparison and selection of port schemes and transportation layout optimization,which improves the science and communication efficiency of the design.
