摘要
巴基斯坦N-J水电站地下厂房是整个工程施工的关键线路,该厂房开挖具有跨度大、高边墙上孔洞分布多、围岩差、变形大、支护工程量大,开挖支护强度高、顶拱和高边墙开挖施工安全风险大等特点。论文通过研究地下厂房快速安全施工技术、优化施工方案、科学组织实施,实现了各项施工目标,为同类工程提供了重要的参考经验,其技术成果在类似地下工程施工中具有广阔的应用前景。
Pakistan N-J Hydropower Station underground powerhouse is the key line of the entire project construction,excavation with large span and high side wall holes distribution of surrounding rock, and large deformation, supporting large quantities, the excavation and supporting of high strength, high arch and side wall excavation construction safety risks and other articles by carefully studying the fast and safe construction technology of the underground powerhouse, optimization of construction scheme, scientific organization and implementation, to achieve the goal of construction, provides an important reference experience for the similar projects, the technology has a wide application prospect in the similar underground engineering construction.
