软岩巷道喷锚支护技术参数优化

Optimization of Parameters on Shotcretebolt Support Technique of Drift in Soft Strata

在综合考虑围岩强度、岩体结构、开挖形式、技术条件、经济指标等影响因素的情况下，建立了巷道支护参数优化的二级模糊综合评判模型。实践证明，运用这一模型对多因素。

In the condition of synthetically considering the influence factors such as strength of enclosing rock, rock structure, excavated form, technical conditions and economic index etc, the author sets up a twograde comprehensive fuzzy judgement model for optimization of parameters in excavation support. The practices proved that this model is feasible and effective to the optimized selection of excavation support parameters with many factors and more fuzziness.
