The anchoring eccentricity of the bolt and cable bolt is a common problem in geotechnical support engineering and affects the ability of the bolt and cable bolt to control the rock mass to a certain extent. This paper reports on numerical simulation and laboratory experiments conducted to clarify the effect of eccentricity on the anchoring quality of the bolt and cable bolt, and to establish an effective solution strategy. The results reveal that the anchoring eccentricity causes unbalanced stress distribution and the uncoordinated deformation of the resin layer, which results in higher stress and greater deformation of the resin layer at the near side of the rod body. Additionally, as the degree of anchoring eccentricity increases, the effect becomes more significant, and the resin layer of the anchoring system becomes more likely to undergo preferential failure locally, which weakens the load-bearing performance of the anchoring system. This paper develops an innovative bolt anchoring rectifying device (B-ARD) and cable bolt anchoring rectifying device (C-ARD) on the basis of the structural characteristics of the bolt and cable bolt to better ensure the anchoring effect of them. The working effects of these two devices were verified in detailed experiments and analysis. The experimental results show that the anchoring rectifying devices (ARD) improve and ensure the anchoring concentricity of the bolt and cable bolt, which will help improve the supporting performance of them. The paper provides a convenient and effective method for improving the anchoring concentricity of the bolt and cable bolt, and provides a concept and reference for technical research on improving the effect of roof bolting.

锚索锚杆锚固偏心是岩土支护工程中的普遍问题，在一定程度上影响锚索锚杆对岩体的控制能力。本文报告了数值模拟和实验室实验，以阐明偏心距对锚杆和锚索锚固质量的影响，并建立有效的解决策略。结果表明，锚固偏心导致应力分布不平衡，树脂层变形不协调，导致杆体近侧树脂层应力较大，变形较大。此外，随着锚定偏心度的增加，效果变得更加显着，锚固系统的树脂层更容易发生局部优先破坏，削弱了锚固系统的承载性能。本文根据螺栓和锚索的结构特点，研制了一种创新的锚杆锚固纠偏装置（B-ARD）和锚索锚固纠偏装置（C-ARD），以更好地保证它们的锚固效果。这两种装置的工作效果在详细的实验和分析中得到了验证。试验结果表明，锚固纠偏装置（ARD）提高并保证了锚杆和锚索锚杆的锚固同心度，有利于提高锚杆的支护性能。为提高锚杆和锚索锚杆的锚固同心度提供了一种方便有效的方法，
