钢管混凝土支架性能试验及其在动压巷道支护中的应用

Steel Tube Confined Concrete Supports (STCCS) Supporting Capability Test and Its Application in Dynamic Pressurized Roadway

摘要: 钢管混凝土支架的承载性能主要取决于其抗压性能和抗弯性能，实验测试了钢管混凝土短柱的抗压强度和支架圆弧段的抗弯能力。并针对受采动压影响严重的采区上山进行了巷道钢管混凝土支架支护方案设计，支护后巷道变形量小，巷道围岩稳定。

Abstract: Bearing capacity of steel tube confined concrete supports mainly depended on its compression performance and flexural properties. It experimental tested the compressive strength of steel tube confined concrete short columns and support arc segment flexural capacity through laboratory test. It also gave roadway steel tube confined concrete supports supporting design aiming at mining area up-hill which was affected severely by dynamic pressure. After supported the roadway surrounding rock was stable with little deformation.
