关口水电站地下厂房岩壁式吊车梁设计

岩壁式吊车梁是一种新型结构形式，目前尚无规范可循。关口水电站地下厂房岩壁式吊车梁的设计，采用平面力系平衡的方法来分析梁的稳定，其中壁座倾角、锚杆参数选取是岩壁式吊车梁设计的关键。对中小型水电站来讲，按照施工技术要求：把好施工质量关，是岩壁式吊车梁成败的关键。

Design of Rock Bolted Crane Beam in the Underground Powerhouse of Guankou Hydropower Station

The rock bolted crane beam is a new form of structure and there are at present no criteria to be followed in itsdesign. This paper describes the design of the rock bolted crane beam in the underground powerhouse of the Guankou Hydropower Station. The design adops the method of balancing the plane stress sysem in analysing stabilty of the crane beam.The key to the design of the rock bolted crane beam is the selection of its rock ledge inclination angles and anchorparameters. For construction of medium and small hydropower stations, success or failure or constructing a rock bolted crane beam depends on implemntation of construction specifications and proper control of construction quality.
