摘要
网壳结构是以杆件为基础,按照一定的规律组成的空间杆系结构。该结构刚度大,重量轻,可以跨越较大的跨度。将地面网壳结构的这种优良力学性能引入地下工程中,通过理论分析、支护方案设计、现场应用与监测、整体效果评价,最终得出该技术在软弱破碎巷道支护中技术可行、经济合理。
Reticulated shell is a kind of spatial skeletal structure consisting of bar member according to certain law.This structure has high stiffness,lighl weight and large span.This surface reticulated shell with excellent mechanical performance was used to the underground engineering.Through theoretical analysis,the designing of the support plan,field application and monitoring and the overall effect evaluation,it is proved that this technique has technical feasibility and reasonable economicy in soft and broken roadway support.
