地下厂房优化设计

随着岩石开挖技术的提高，越来越多的水电站采用地下厂房。顺此，对地下厂房进行优化设计很良具有实际意义。结合木座电站地下厂房的设计，以减小地下厂房尺寸为主要目的，采取了一系列对厂房进行优化设计的具体措施，并将原设计和优化设计进行了对比说明。此外，还针对厂房顶部的锚索、洞室周围的排水和岩壁吊车梁三方面关键问题进行了讨论。

Discussions on optimizing methods of underground powerhouse

With the advanced rock excavation methods, underground powerhouses are widely used. So, it is necessary to optimize the design of underground powerhouse. The main aim of this paper is reducing the size of underground powerhouse. It includes many optimizing n, easures of underground powerhouse, which will be applied to Muzuo Hydroelectric station in Sichuan Province. And it explains how to apply these measures to design, by contrasting tbrmer with optimized. Moreover, it discusses three key problems involved in cables in the powerhouses crown, drainings around caverns and crane beams ancbored at rock mass.
