巷道位移影响度分析的正交试验法

Orthogonal test method of roadway displacement analysis

用正交试验法研究了多个参数同时变化对围岩变形影响的程度,试验为7因素7水平。分析结果表明:在巷道位移影响度中,弹性模量、摩擦角、粘聚力为显著影响因子,洞室尺寸、侧压力系数、泊松比、地应力为次要影响因子。

Research by orthogonal test multiple parameters simultaneously affect change on the degree of rock deformation, this test is 7 levels and 7 factors. The results of analysis show that, in the factors that effect roadway displacement degrees, elastic modulus, friction angle, cohesion were significant factors, cavity size, lateral pressure coefficient, poisson＇s ratio, the earth stress were factors for the secondary effect.
