摘　　要：随着国内外水利水电工程的发展,越来越多的地下工程设计有斜井,且斜井弯段长度较长。受整体地形和电站布局影响,斜井大部存在空间转弯,对于斜井施工,尤其是存在空间转弯的斜井开挖是整个项目施工的重点与难点。为了保证施工生产的安全,加快斜井的开挖进度,减少由于布置机械和提升系统而需进行的技术研究,降低工艺措施引起的费用的投入。因此对这些问题进行技术研究,提出合理方案,为工程顺利施工提供指导。With the development of water conservancy and hydropower projects at home and abroad,more and more underground engineering designs have inclined wells with long bend length.Influenced by the overall topography and the layout of the power station,space turns exist in most of the inclined shaft.For the construction of inclined shaft,especially the excavation of inclined shaft with space turning is the key and difficult point of the whole project.In order to ensure the safety of construction and production,speed up the excavation progress of inclined shaft,reduce the technical research required due to the arrangement of machinery and lifting system,and reduce the investment of technical measures,the construction company of Changheba Hydropower Station carries out technical research on these problems and proposes reasonable schemes to provide good guidance for the smooth construction of the project.
