岩锚梁稳定性的灰色关联分析

为了分析岩锚梁的稳定性，基于灰色系统理论，利用灰色关联分析方法，对影响岩锚梁稳定性的因素进行了关联度计算，得出了各因素对稳定性的影响程度及各因素间的相关程度；指出了混凝土浇筑时引起的温度变化是影响岩锚梁稳定性的关键因素，提出在施工过程中应采取相应的养护措施。为岩锚梁的施工及投入运行提供了可靠的理论依据。

Grey relation analysis in stability for rock -bolt crane girder

To analyze stability of rock-bolt crane girder, based on grey system theory, the relational degree of correlative factors on stability was calculated with grey relational analysis method. And the influence degree of factors on stability of rock-bolt crane girder and the correlativity between factors were gained. It was pointed out that the change of temperature due to concreting was the key to stability of rock-bolt crane girder. At the same time, the engineers were advised to adopt relevant maintaining measure in construction. And reliable academic basis for construction and use were provided.
