十三陵电站大跨度地下厂房施工

Construction of the Underground Powerhouse with a Large Span of the Ming Tombs Pumped Storage Hydroplant

十三陵蓄能电站地下厂房，地质条件复杂，施工跨度大，支护型式多，施工技术质量要求高，如何保证地下厂房开挖安全与稳定至关重要。地下厂房施工自始至终与观测紧密结合．实践证明地下厂房的设计支护参数与施工是成功的．为我国的水电施工积累了一定的经验。

Safety and stability are essential for the underground powerhouse of the Ming Tombs Pumped Storage Hydroplant bccause of its complicated geological conditions with a large construction span, more types of supports, and high quality requirement. The practice showed that the designed support parameters and construction are successful. Some experiences have been accumulated for the hydro sector in China.
