摘要
某工程地下厂房岩壁吊车梁的设计尺寸和承载负荷均位于国内前列，通过对国内最大规模的岩壁吊车梁原位承载试验，表明漫湾岩壁吊车梁是安全可靠的；另外，通过试验成果与计算成果的对比，对岩壁吊车梁的设计和优化提出了建议。
Design size and carrying capacity of the rock anchor beam in underground powerhouse of Manwan hydropower station lies in leading position in domestic civil engineering projects. The result of the rock anchor beam experiment which is the largest of domestic civil engineering indicated that the rock anchor beam is safe under various working conditions. The paper presents some optimal suggestions about the rock anchor beam after contrasting the experiment result and FEM calculation result.
