摘要
应用弹性地基梁理论对锚拉支架中锚杆和拉杆的横向位移、受力状态等进行了分析,提出了一种简化计算模型。由该简化计算模型推导的公式可作为锚拉支架支护机理分析的基础和参数设计的计算方法。
The analysis on traverse displacement and load state of the bolt and pull rod in a truss is made based on the theory of beams on elastic foundations, and a simplified calculation model for trusses is proposed. The equations of the model is able to be the foundation of the mechanism analysis of truss support and the calculation method of parameters selected for a truss.
