杨房沟水电站地下厂房开挖施工技术
|
摘要
杨房沟水电站是我国首个采用设计施工总承包模式进行建设的百万千瓦级大型水电站,地下厂房施工是工程建设的两大主线之一。针对其花岗闪长岩的特性,采取了地质跟进、动态进行设计施工的方式,确保了工程和开挖施工安全,并提前半年完成了地下厂房开挖的目标,为混凝土转序奠定了坚实的基础。
Yangfanggou Hydroelectric Power Station is the first mega-kilowatt hydroelectric power station in China to be constructed by the general contracting mode of design and construction. The construction of underground powerhouse is one of the two main lines of construction. In view of the characteristics of its granodiorite,the way of geological follow-up and dynamic design and construction is adopted to ensure the safety of engineering and excavation construction,and the excavation goal of underground powerhouse is completed half a year ahead of schedule,which lays a solid foundation for concrete sequencing.
