摘　　要：在大型地下洞室中采用岩锚吊车梁可以缩窄洞室跨度 ,有利于围岩稳定 ;及早形成运输能力 ,加快施工进度。论文对龙滩水电站地下厂房采用岩锚吊车梁的设计思路予以重点介绍 ,并从设计角度提出对施工技术、缺陷部位的处理。The use of rock bolted crane beam in large caverns can shorten the cavern span and improve the stability of surrounding rock masses, thus obtain an early access to transportation within the cavern and accelerate the construction progress. Emphasis is put on the introduction to the design principle of the rock bolted crane beam used in the underground powerhouse of Longtan project, and requirements are put forward on construction technique, treatment of defect parts, loading test and observation design in response for the design of the crane beam.
