京杭运河万年闸复线船闸平面布置方案

受一线船闸、桥梁、泄水闸、调水泵站和防洪大堤等已建建筑物的制约,京杭运河万年闸复线船闸的平面布置条件较为复杂。船闸平面布置时结合既有建筑物的限制条件、船闸通航条件、相邻建筑物的安全和正常运行、船闸运行管理、工程协调美观性、施工条件以及工程投资等方面对闸位进行比选,确定最优的船闸闸位方案,在引航道布置时结合设计船型的实际情况和一线船闸引航道的现状条件采用弹性停泊段和共用靠船墩等创新方案,对在工程集中区域布置多线船闸具有借鉴意义。

General layout of second-line ship lock of Wannian navigation junction of Beijing-Hangzhou Canal

Restricted by the existing structures of the first-line ship lock,bridges,sluice,water transfer pump station and banks,the general layout of second-line ship lock of Wannian navigation junction of Beijing-Hangzhou Canal is complex.The lock positions are compared in combination with the restrictions of existing buildings,navigation conditions,safety and operation of adjacent buildings,operation and management,coordination and aesthetics,construction conditions and investment,and the optimal lock position is determined.According to the actual situation of the design vessel type and the conditions of the approach channel of the first-line lock,innovative schemes such as flexible mooring area and common berthing pier are adopted in the layout of the approach channel.It may serve as reference for the layout of multi-line lock in the concentrated area of buildings.
