在高山峡谷地区建设大型水力发电站,修建规模巨大的地下水工建筑物往往是不可避免的。这些水工建筑物包括大断面的导流隧洞、泄洪隧洞、引水隧洞以及体型庞大的调压井、闸门井等等。在某些情况下,发电厂房如果布置在地下有利或必须放在地下,那么还包括修建地下厂房等洞室。这样,地下建筑物就成为整个水电工程的主要组成部分,庞大的地下工程量必然成为影响电站建设速度的主要因素。因此,研讨如何加快地下工程施工,对这种类型电站建设有着十分重大的意义。本文介绍如何在不利的地质条件下,安全、快速、优质地
It is often inevitable to build large-scale hydropower plants in high mountain canyons and to build large-scale underground structures. These hydraulic structures include diversion tunnels with large sections, flood discharge tunnels, diversion tunnels, and large surge tanks, gate wells and the like. In some cases, the powerhouse, if placed underground, or must be placed underground, it also includes the construction of underground power plants and other caverns. In this way, underground buildings become the main component of the entire hydropower project, a huge amount of underground engineering will inevitably become the main factor affecting the speed of power plant construction. Therefore, to study how to speed up underground construction is of great significance to the construction of this type of power station. This article describes how to safely, quickly, and optimally in unfavorable geological conditions
