巴基斯坦SK水电站地下厂房顶拱层开挖施工技术研究

Study on the Construction Technology of Roof Arch Layer Excavation for Underground Powerhouses of SK Hydropower Station in Pakistan

巴基斯坦SK水电站地下厂房位于整个工程的关键线路,其所处地质条件差,开挖工期紧,厂房顶拱层开挖成功与否关系到整个项目的成败。文章通过对厂房顶拱层施工布置、施工难点、施工程序及施工方法的研究分析,确保了合同履约。相关参数可供类似工程借鉴和参考。

The underground powerhouse of SK Hydropower Station in Pakistan is located in the key line of the whole project.Its geological conditions are poor and the excavation period is short. The success or failure of the excavation of the roof of the powerhouse is related to the success or failure of the whole project. Through the research and analysis of the construction layout, construction difficulties, construction procedures and construction methods of the roof of the powerhouse, the contract performance is ensured. The related parameters can be used for reference in similar projects.
