三峡水利枢纽技术设计中一些重大技术问题的论述

Discussion on the several major problems in the design of the Three Gorges Project

三峡水利枢纽在技术设计中，研究解决、决策了大坝泄洪消能，岸坡厂房坝段基础深层稳定，电站引水管道结构型式，电站排沙排漂，永久船闸输水系统及水力学，引航道布置及通航水流条件、高边坡稳定，升船机承重结构稳定，水轮发电机组及金属结构中的永久船闸人字门、启闭机、充水泄水间门，升船机承船厢提升及平衡系统等一些重大技术问题。

In the technical design of the hree Gorges Project, the following major technical problems have been identified and solvd, that is energy dissipation for flood discharging through the dam;deep foundation stability in thepowerhouse dam section on the bank; structural types of diversion pipeline of hydropower station; sediment anddrifter flushing for the station; the conditions of water conveyance system, hydraulics, layout of approach channeland navigable flow for permanent navigation lock; stability of high side-slope; loadbearing structure stability of shipelevator; miter gate of permanent navigation lock, hoisting equipment and water filling and discharging valves forthe hydraulic turbine generator unit and metal structure;lock chamber lifting and balance system of ship elevator.
