采用弹性和复合材料力学的理论，对巷道锚杆支护采用两种不同的计算模型，分析了它们对巷道围岩控制效果的影响，说明了选择研究方法的重要性。对计算模型的简化处理必须以其作用机理为根本，否则，将导致偏离实际的结果 Using the theory of elasticity and composite mechanics, two different calculation models are used for bolt support of roadway, and their influence on surrounding rock control effect is analyzed. The importance of choosing research method is illustrated. Simplification of the computational model must be based on its mechanism of action as a fundamental, otherwise, will lead to deviation from the actual results
