长江下游太平洲捷水道设计航道尺度标准

Taipingzhou shortcut waterway channel scale standard in the lower Yangtze River

在对水道航道条件进行分析的基础上,考虑跨河建筑物净空尺度的限制条件,提出太平洲捷水道仅能开辟为3 000吨级及以下航道。通过核算太平洲捷水道的航道通过能力,综合分析预测航道尺度提高后,两岸岸线开发和分流主航道船舶所带来的通航船舶尺度和数量的变化,合理确定了设计代表船型。根据设计代表船型所需航道尺度计算,提出了太平洲捷水道设计航道尺度标准为5.0 m×200 m×450 m(水深×航宽×弯曲半径),可为太平洲捷水道的设计航道尺度标准确定提供参考。

Considering the limiting waterway conditions, we point out that Taipi conditions of river crossing buildings clearance based on the analysis of ngzhou shortcut waterway can only be opened up to waterway of 3 000 DWT or below. After checking the waterway capacity of Taipingzhou shortcut waterway and analyzing comprehensively the change of navigation ship dimensions and amounts due to the development of both sides shoreline and diverted ships from the main channel after the channel dimensions are increased, we determine the designed typical ship type. According to the channel dimensions needed for the designed typical ships, we recommend the designed channel scale for Taipingzhou waterway is 5.0 m × 200 m ×450 m（ water depth x navigation wide× bending radius）, which may serve as reference for the development and utilization of Taipingzhou shortcut waterway.
