| 摘 要： | 漫湾水电站二期工程地下厂房吊车梁采用岩壁吊车梁结构。设计采用刚体力系平衡法和有限无法进行计算，并借鉴了鲁布革等水电站岩壁吊车梁设计的成功经验。针对漫湾工程岩壁吊车梁地段地质条件较差的问题，设计中采用了混凝土置换等措施进行加强锚固。通过承载试验成果及一段时间的运行表明，岩壁吊车梁体形及锚固措施设计是合理的。

| Abstract: | The crane girder of the second-phase Project of Manwan Hydropower Station in underground powerhouse is concrete girder bolted to rock-face,During design,the FEM && forces balanced of rigid body are applied,and absorbed the successful experiences of concrete girder bolted to rock-face.Encountered with the poor geological conditions at the girder base,the concrete replacement measure is adopted to strengthen to surrounding rock mass.Through bearing capacity test and quite a long period of operation,the structure and anchorage measures of concrete crane girder are proved to be reasonable. |
