| 摘 要： | 为了对巷道支护机理进行研究，揭示锚固复合承载体的承载作用，采用相似模拟试验，在均质围岩条件下，使用不同的锚杆支护参数进行巷道支护，对巷道施加破坏性载荷，分析了不同阶段下锚固复合承载体的测点应力与表面位移的关系，得出了锚固复合承载体的承载特性的影响规律。研究为确定巷道合理的支护参数提供了理论依据。

| Abstract: | In order to study the roadway support mechanism and reveal the bearing capacity of the anchor composite carrier，similar simulation tests are carried out in this paper，under the condition of homogeneous surrounding rock，different bolt support parameters are used to support the roadway，and the roadway is destructive，the relationship between the point stress and the surface displacement of the anchored composite carrier under different stages is analyzed.The influence law of the bearing characteristics of the anchor composite carrier is obtained.The study provides a theoretical basis for reasonable support parameters of the roadway. |
