摘要
锚杆锚固质量评价目前以锚杆长度和灌浆密实度2个指标作为评判依据,但在工程应用中,2个指标均存在不同程度的缺陷。为有效解决以上问题,本文基于锚杆的受力特点,选择应力状态相关参数作为评价锚杆锚固质量的指标。通过探讨数值模型建立的可行性和实体试验模型的可操作性,认为可建立应力指标与锚杆锚固质量之间的关系,为快速评价锚杆锚固质量提供依据。
The fixed effects of metal pole are evaluated by using the pole’s length and the grouting density at present,but they have defects more or less.To solve the problem,we evaluate fixed effect of the metal pole using indicators related to stress status,based on the characteristics of stress.Through analysis on the feasibility of numerical model and the operability of test model,the stress status is connected with the fixed effect to provide evidence for evaluating fixed effect in a fast way.
