| 摘 要： | 通过对国家标准《内河通航标准》(GB50139-2004)[3]的分析和计算,找出了影响航道水深的主要因素,根据特殊限制性航道———中间渠道和渡槽的运行特点,推求出它们水深的计算方法和结果。航道水深由船舶吃水和富裕水深组成,富裕水深中考虑了船体下沉量、通航建筑物运行引起的水位变幅、船行波以及触底安全富裕量。并参照《内河通航标准》给出了航道的弯曲半径,形成了完整的特殊限制性航道尺度系列。

| Abstract: | 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. |

| Keywords: | inland river navigation standard intermediate channel aqueduct depth of channel |
