三峡大坝二期工程结构设计与优化

Structural design and optimization of the second-stage works of the Three Gorges Project

三峡大坝二期工程施工详图设计中,对大孔口配筋、电站压力管道、左导墙长度、左岸厂房坝段坝顶门机梁等的设计进行了优化,并对左厂1～5号坝段深层抗滑稳定问题和临时船闸1、3号坝段续建期的稳定和应力问题进行了深入研究。

The design of the reinforcement of the large openings, the penstocks of the power plant,the length of the left diversion wall,and the gantry girders on the top of the powerhouse dam-section are optimized during the working drawing period of the second-stage works of the Three Gorges Project. This paper also describes the design of the stability against sliding of the left powerhouse dam-section 1 to 5,and the design of the temporary ship-lock dam-section.
