摘要
为向矿区铁路应用提供参考,分别采用普通石子和煤矸石作为路堤填料,对格宾结构单体进行了单轴压缩试验研究,得到了其力学行为和单轴受压的应力-应变关系.试验结果表明:在不同颗粒级配情况下,格宾结构单体单轴受压的应力-应变特征和力学行为规律不明显;石子作为填料的格宾结构单体的抗压强度远远大于煤矸石作为填料的格宾结构单体的抗压强度.理论计算结果表明,石子作为填料的格宾结构的承载力完全满足路堤承载力的要求.
In order to provide a reference for the application of Gabion structures in mine railway,their mechanical behavior and stress-strain relationship under uniaxial compression were obtained through the uniaxial compressive tests of Gabion structures filled with gravels or coal gangues.The experimental results show that under uniaxial compression,the mechanical behavior and stress-strain characteristics of Gabion structures with different grain compositions have no obvious regularities.The compressive strength of a Gabion structure filled with gravels is larger than that filled with coal gangues.And Gabion structures filled with gravels can meet the requirements of the load-bearing capacity of railway bridge embankment.
