摘　　要：根据空间壳体力学原理,通过模型试验研究了聚丙烯纤维混凝土钢筋网壳的力学性能及复合衬砌的变形、破坏形态与发展规律。该支护体系的应用,实现了三维钢筋支架与混凝土力学特性在深井破碎性软岩巷道支护中的复杂应力的转化效应,从而达到对深部巷道围岩稳定的控制目标,能有效地支护高地压大变形巷道、跨采动压巷道、冲击地压巷道以及大断面硐室等。According to the principles of mechanics of three-dimensional shell,through the model test,the mechanical properties of reinforced net shell of polypropylene fiber reinforced concrete and the deformation of the composite lining,the destruction morphology and the regularity of its development are studied.The application of the support system can achieve the transformation effect of the complex stress between a bracket of three-dimensional reinforced concrete and the mechanical properties in the deep well broken soft rock roadway support,so as to achieve the control objective of the stability of the deep roadway surrounding rock.And it can effectively support the high ground pressure large deformation roadway,cross-mining dynamic pressure roadway,rock burst roadway as well as the large cross section chamber.
