Consideration of depth definition of special restricted channel from navigation standard of inland waterway

From analysis and calculation to the inland river navigation standard(GB1350139-2004),main factor that influences channel depth is found out.According to the characteristics of special restricted channel(namey,intermediat channel and aqueduct),the calculation method and result of standard depth of channel are deduced.The standard depth of channel includes both draft of the ship and depth clearance.Vessel squat,water level amplitude caused by navigation structures,ship wave and safe deal of contact bottom are considered in calculating depth clearance.Consult the inland river navigation standard,radius of bend is given out.Integrated dimensions series of special restricted channel come into being.
