【Abstract】 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.更多还原
