摘　　要：在大、中型水电站建设前期,往往遇到厂房桥机尚不具备或现场起吊设备不能满足吊装水轮机座环的难题。积石峡水电站曾面临同样的难题,在施工单位经过科学精密的计算和精心组织,采用了人字桅杆渡吊的方法将3台机组座环安全、顺利地吊装就位,确保了电站3台机座环安装及发电节点工期的圆满完成。In the early construction period of large and medium-sized hydropowcr stations, the installation of stay ring of turbine is a problem because there is no bridge crane or the lifting equipments in situ which can meet the requirements. This problem is also faced in the installation of stay rings in Jishixia Hydropowcr Station. After scientific calculation and careful organization, the crossing-hanging-lifting lechnology with a herringbone bridging is used to install the stay rings of three units. The installations arc successful and guarantee the installation duration.
