枢纽船闸与上、下游桥梁之间最小距离的分析

Analysis of the minimum distance between the hydro-junction ship lock and the upper-stream or the down-stream bridges

根据相关规范,将枢纽布置、船闸布置、桥梁布置及船舶通航要求采用概化模型进行分析,得到枢纽船闸(引航道口门)与上、下游桥梁之间最小距离的要求。试验结果表明:该最小距离要求是合理的,对枢纽(或桥梁)规划设计或规范制定具有参考意义。

According to the layout requirements of the hydro-junction, ship locks, bridg- es and the navigation conditions, a conceptual model is established to obtain the minimum distance requirements between the hub ship lock（approach channel entrance） and the upper-stream and down-stream bridges. The generalized model test shows that the minimum distance requirement is reasonable and the results can offer a reference value for the planning and design of hydro-junction or bridges.
