三峡工程机电及金属结构设计研究

Studies on design of electric&mechanical equipment and metal structures of TGP

长江三峡工程是世界上在建的巨型水电工程，其每个单项工程都相当于一个大型工程，三峡水利枢纽的机电和金属结构工程规模和技术复杂程度达到当今世界水电工程之最。通过介绍在三峡工程技术设计阶段开展重点技术问题设计研究的情况，针对三峡工程的技术特性，概述了机电设计中诸如水轮发电机组选择、电气、继电保护和通信等方面的设计原则、目标要求与方法，以及进行重点技术研究的简况；同时扼要描述了双线连续五级船闸，垂直升船机以及电站进水口和泄水闸门等金属结构设计、制造和安装的技术特点和要求，并着重对金属结构设计中的重点研究问题和自动化监控系统作了简要介绍。

Three Gorges Project is a huge one under construction. All of its component works are equivalent to individual large projects, of which the electric & mechanical equipment and metal structures' scale and complexity are rare in the present world. The following contents are presented: the conditions of studying the key design projects during the technical design phase of TGP; the principles, target requirements and method of the electric and mechanical equipment design; the technical features and requirements of design, manufacture and installation of the metal structures of the double-line flight shiplocks, the vertical shiplift, the power intakes and the overflow dam et al. In addition, the specially studied problems during the metal structure design and the automatical monitoring system are particularly presented.
