圆形条带碹支护的塑性极限分析

Analysis on the Plastic Limits of Partial Arch Lining

条带喧支护是软岩巷道的一种特殊的支护形式。本文利用塑性极限分析方法，导出圆形条带喧支护地压的上、下限解答，算例表明，采用这种分析方法是有效的，该结果为条带喧进型、支护设计与参数计算提供了理论依据。

Partial arch lining is a special kind of support used forroadways driven in soft strata.By means of plastic limitanalysing methld, the paper inferred the resolution of the upper and lower limits of ground pressure on the arch.The practical calculation shows that the method is effective onchoosing the construction of partial arch lining and oncalculating the design parameters.
