研究了锚拉支架中锚杆的横向抗力，分析了锚杆横向效应对加固破碎圈岩石的成拱作用，推求了锚拉支架的拉杆拉力、锚杆横向抗力与加固作用的关系，获得的理论公式可以用于锚拉支架的分析设计，应用实例证实了其可行性。
The lateral resistance of the anchor rod in the anchorage bracket was studied. The arching effect of the anchor rod lateral effect on the reinforcement broken ring rock was analyzed. The relationship between the rod tension of the anchor bracket, the lateral resistance of the anchor rod and the reinforcement effect was obtained. The obtained theory The formula can be used in the analysis and design of anchorage bracket, and its application is proved to be feasible.
