摘　　要：煤矸石是洗煤过程中产生的工业固体废料,在我国堆放量大、占地面广,堆放过程中产生的有害物质会造成严重污染,破坏环境。煤矸石替代骨料配制混凝土,不仅可以降低煤矸石储量,同样可以减少天然集料的使用,具有一定的经济效益。煤矸石混凝土与钢材的结合,使结构承载力高、塑性和韧性好的优点更加突出。文章采用文献调查法,对钢管煤矸石混凝土的受力性能进行综述,详细阐述煤矸石对混凝土承载力的影响及低温环境下钢管混凝土受力性能的研究现状,并对钢管煤矸石混凝土的发展趋势进行展望。Gangue is industrial solid waste produced in the process of coal washing.It is piled up in large quantities and covers a wide area in China.The harmful substances produced in the process of stacking can cause serious pollution and also damage the environment.Using gangue instead of aggregate to prepare concrete cannot only reduce the reserves of gangue,but also reduce the application of natural aggregate,thus having certain economic benefits.The combination of coal gangue concrete and steel tubular makes the advantages of high bearing capacity,good plasticity and toughness of the structure more prominent.This paper uses the method of literature investigation to summarize the mechanical properties of gangue concrete filled steel tubular,elaborates the influence of gangue on concrete of the bearing capacity and the research status of the mechanical properties of concrete filled steel tubular under low temperature environment,and looks forward to the development trend of gangue concrete filled steel tubular.
