| 摘 要： | 岩锚吊车梁的设计,目前国内尚无规范可循,传统的计算方法受地质条件和开挖爆破等不确定因素的影响,难以对其进行精确计算。小湾水电站地下厂房岩锚吊车梁进行了1:1模型试验,通过两次常规加载和一次超载试验,对岩锚吊车梁的整体变形特征和安全度进行了评价,指导了岩锚吊车梁的设计和施工。

| Abstract: | The design of crane girder bolted to rock has no code to conform in China at present.The traditional calculation methods are greatly affected by uncertain factors,such as geological conditions and excavation.Hence it's hard to be calculated in sophisticated way.The 1:1 scale model test for the crane girder bolted to rock in Xiaowan underground powerhouse are implemented.Through twice traditional loading and once over-loading tests on the crane girder bolted to rock,the integral deformation characteristics and safety are evaluated,these results are positively guide the design and construction of the crane girder bolted to rock. |
