为了优化柔性注压锚杆的设计,进一步分析了新型柔性注压锚杆的结构特点,应用有限元法对锚固系统进行接触分析,计算并研究了在锚固情况下锚杆体与围岩相互作用的接触应力关系,得出了锚杆结构中各主要设计参数与不同的围岩压力对锚固性能的影响规律,以及该锚杆可以适用于多种不同围岩条件的结论,为该锚杆的优化设计和使用提供了依据。
In order to optimize the design of flexible injection bolting, the structural characteristics of the new flexible injection bolting are further analyzed. The contact analysis of the anchoring system is carried out by finite element method. The interaction between the bolting body and the surrounding rock is calculated and studied. The relationship between the contact stress and the main design parameters of the anchor structure and different pressure of the surrounding rock on the anchoring performance of the law and the anchor can be applied to a variety of different rock conditions concluded that the anchor Provide a basis for the optimal design and use.
