| 摘 要： | 采用理论分析与试验研究相结合的方法，通过对大量钢管煤矸石混凝土轴心受压短柱试验数据的计算，分析，推导出钢管煤矸石混凝土中核心混凝土的极限抗压强度及横向变形系数；分析了含钢率及混凝土的强度等级对煤矸石混凝土极限抗压强度的影响；指出低标号的煤矸石混凝土更适合与钢管相结合形成组合材料，以便充分发挥钢管对核心混凝土的约束作用。

| Abstract: | Theoretical analyses and tests enables the maximum compressive str ength and lateral deformation coeffi-cient of core concrete of gangue concrete filled steel tubes to be established.The maximum compressive strength of gangu e concrete restrained by steel tube is subject to the influence of steel ratio a nd gangue concrete standard strength under axial load.The gangue concrete with lower strength is more suitable to be filled into steel tube to form composite m aterial,thereby restraining the action of steel tube on core concrete in a more efficient way. |

| Keywords: | steel tube gangue concrete short column under axi al load maximum compressive strength re straining function lateral deformatio n coefficient |
