摘要
本文根据端部锚固锚杆桁架的支护机理,从改善裂隙顶板的受力状态和增加拱座处抗滑摩擦阻力出发,首次提出了此类支护型式参数的设计公式和分析解析式,为工程分析和设计提供了理论工具。根据这些原理设计的回采巷道已成功地应用于矿山生产,表明了方法的实用性。
In this paper, a group of formulas for the analysis and design of truss systems with point anchoring bolts has been obtained on the basis of the supporting mechanism, such as improving the stress state of the mine roof and increasing the shear resistance at the abutments of an arched beam. The appoximate solutions proposed are useful for the design of roof truss systems.
