红花二线船闸平面布置方案

Plane arrangement of Honghua second-line ship lock

在已建船闸旁增建二线船闸,应综合考虑相邻建筑物安全性、通航水流条件、施工条件及工程投资等因素。以红花二线船闸平面布置为例,在分析已建枢纽布置及结构物特点的基础上,确定二线船闸工程建设目标。重点论述二线船闸建设时选址及平面布置思路及方法,并对不同方案进行技术经济方案比选,对增建二线船闸工程的项目具有借鉴意义。

The safety of the existing structures,flow conditions,construction conditions and investment should be considered if building a new ship lock next to the one already built.Taking Honghua second-line ship lock for example,we analyze the layout of the existing hydropower complex and characteristics of the existing structures,and determine the construction object of the second-line ship lock.The principles and methods of site selection and planning are expounded,and technical and economic comparison is conducted among different schemes,which may serve as reference for similar projects.
