摘要
广东省已建成了广州抽水蓄能电站A厂、B厂,惠州抽水蓄能电站A厂、B厂,目前正在建设的有清远抽水蓄能电站和深圳抽水蓄能电站等。抽水蓄能电站属于高水头、埋藏深的地下电站,地下厂房洞室群上下游均处于水库高水位以下的复杂地质和地下环境条件下,地下厂房位置选择、开挖支护和地下截排水控制体系至关重要。本文主要介绍广东抽水蓄能电站在复杂的地质环境条件下地下厂房位置选择方法、地下厂房的施工控制和高压岔管、地下厂房系统的防渗排水控制体系,并通过总结,为其他抽水蓄能电站及类似重大地下工程提供参考。
In Guangdong Province, China, Guangzhou Pumped Storage Power Station（Phase Ⅰ Ⅱ） and Huizhou Pumped Storage Power Station（Plant A and B） have been built, while another two, i.e. Qingyuan Pumped Storage Power Station and Shenzhen Pumped Storage Power Station are under construction at present. The pumped storage power station（hereafter simplified as PSPS） is a sort of deeply buried underground power station with high head. Due to the upstream and downstream of underground power house complex are located in complicated geologic underground environment which below the high water level of reservoir, it is of great importance for site selection, excavation and support, as well as underground water interception and drainage control system of underground power house. This paper mainly introduces the methods of site selection, power house construction control and seepage prevention and drainage control system of underground power house, especially for manifold, which have been adopted in PSPS in Guangdong under complicated geologic and underground environment. Experience learned from those projects can provide reference for other pumped storage power stations and similar large-scale underground projects.
