摘要
小浪底工程地下厂房顶拱分两期支护，一期为钢筋网喷混凝土加岩石张拉锚杆，二期为顶拱系统预应力锚索。施工中我们从开挖与支护方案审查、质量控制到进度控制，整个施工过程严格把关，关键工序重点控制，保证了工程质量和进度。
Supporting for the top vault of underground plant in Xiaolangdi project is carried out in two stages. In the first stage, concrete was sprayed on steel reinforcing mats and rock anchor bars were tensioned. In the second stage, anchor cables of top anchor system were prestressed. The constructors carried out strict check of the whole process of construction, including checking the plan of excavation and supporting, quality control, schedule control. They focus their attention on the control of key work process and ensure the project quality and the construction speed as a results.
