【摘要】 岩锚吊车梁是一种新型的地下厂房吊车梁结构型式，因它具有减小厂房宽度、节约资金、提前安装吊车方便后期施工等优点，已在水电站地下厂房中得到广泛应用，并且还将会发挥越来越重要的作用。岩锚吊车梁在施工及运行期的工作性态和稳定性是工程设计和施工中所关注的主要问题之一。 本文结合白山发电厂抽水蓄能泵站建设的工程实际，以岩锚吊车梁为主要研究对象，用Drucker-Prager弹塑性本构关系用来模拟地下厂房围岩和混凝土材料，全面考虑混凝土、围岩和锚杆三者的变形对岩锚吊车梁受力状况的影响，利用三维非线性有限元技术仿真模拟地下厂房的逐层开挖过程及吊车轮压载荷作用，对白山泵站地下厂房岩锚吊车梁及其附近围岩的受力、变形和稳定性，作了全面计算分析与评价。通过与现场实测数据对比，计算成果与实测值不仅在数值上符合较好，而且分布规律和变化趋势也完全一致。同时，对影响锚吊车梁受力和变形的主要结构参数进行了数值分析，指出岩锚吊车梁设计和施工中存在的问题及注意事项，具有一定的工程指导意义和参考价值，为今后岩锚吊车梁设计理论和施工方法的研究提供理论依据。更多还原

【Abstract】 The rock bolt crane girder is a new structure model. By comparison with the common crane girder, the rock bolt crane girder has more advantages. For example, it can deduce width of a plant, reduce expenses, contribute to fix the crane in advance giving facilities for final construction, etc. For these reasons, the rocket bolt crane has wide applications in the underground power plant, and will continuously play an important role in the future. The working performance and stability of the rock bolt crane girder has always being an important problem in project design and construction.Combining with the project practice of Baishan pumped storage power house, the articale treats the rock bolt crane girder as the objection of research and gets the concrete and rock mass modeled by the Drucker-Prager elastic-perfectly plastic constitutive relation. It takes full consideration of the effect caused by deformation of concrete, rock mass and anchor rod on rock bolt crane girder, and applies three-dimensional non-linear finite element method to simulate and analyze the effect caused by the stage excavation of Baishan pumped storage power unergrond house’s mid-bottom part and wheel loading on deformation, stress and stability of the rocket bolt crane girde and its nearby surrounding rock mass. Compared with the in-situ results, computing results are proved to be almost consistent with the test in-situ not only in data but in the law of location and the trend of change. By analyzing main structure parameters of rock bolt crane girder, the article indicates main problems and key points in design and construction of rock bolt girder. So it has some implication in reference and guidingin practice, and provides the basis of theory for the development of design theory and construction ways of rock bolt crane girder.更多还原
