| 摘要: |
| 在《船闸总体设计规范》中规定了引航道尺度及布置,以指导工程设计,但签于山区河流枢纽船闸受地质、地形条件的影响,尤其受边界条件的制约,很难满足规范要求.为此,根据枢纽船闸引航道的工程实践,对引航道长度、宽度、制动段、布置形式及停泊位置等问题,进行实践与规范的对照、比较和讨论,提出山区河流枢纽船闸引航道长度可适当缩短,口门可不加宽;引航道布置可为半开敞的直线式、曲线式;停泊段可设在引航道扩大段或口门区内等建议.通过原型代表船型及船队的检验,以供规范修订时参考. |

| Abstract: |
| In the "Code for Master Design of Shiplocks",the scale and the layout of the approach channel are provided to guide the engineering design.However,the shiplock located in the mountain river can’t meet the requirements of design code because it is affected by conditions of geology and topography,especially boundary conditions.Therefore,based on the practical engineering of the approach channel and shiplock,comparison and discussion are conducted for the problems about the approach channel length,width,layout and anchor position.The suggestions are as follows: the approach channel length could be shortened and the entrance is in no need to be widened,the layout of the approach channel could be designed as semi-open straight line style or curved style,anchor area would be set at the expanding part of the approach channel.These suggestions could be provided for design code revision,which should be checked by prototype ships and fleets. |
