摘    要:针对岩锚梁稳定性具有的不确定性、模糊性与灰色性,采用模糊理论与灰色关联理论相结合的方法建立模糊灰色关联分析模型,并对岩锚梁稳定性影响因素进行模糊灰色关联分析,得出各影响因素对岩锚梁稳定性的影响程度及各影响因素间的关联程度。研究结果表明:各因素对岩锚梁的稳定性影响程度不一,围岩形变对其影响最大,其次是锚杆应力和围岩开合度,对岩锚梁稳定性影响最小的是围岩温度。研究结果可为岩锚梁混凝土浇筑施工及投入运行提供参考。

Abstract: Considering the uncertainty, fuzziness and grayness of the stability of the rock-bolt crane girder, fuzzy theory and grey relational theory were used to establish an advanced fuzzy grey relational analysis model, the influence factors for the stability of the rock-bolt crane girder were analyzed by using the advanced fuzzy grey relational analysis model, and the relational degree of the influence factors on stability of the rock-bolt crane girder and the correlativity among the influence factors were gotten. The results show that varying degrees of influence of various factors on the stability of the rock-bolt crane girder are obvious, the maximum influence factor on the stability of the rock-bolt crane girderis the deformation of the surrounding rock, the next are the stress of the anchor and the opening degree of the surrounding rock, and the minimum influence factor on the stability of rock-bolt crane girderis the temperature of the surrounding rock. The research results can provide reference for construction of the rock-bolt crane girder.
