摘　　要：拱形金属支架的承载能力与其受载条件有很大关系，改善支架的受力将有利于承载能力的充分发挥，实施支架壁后充填是改善拱形支架受载状况的有效方法。本文分析了支架壁后充填及其质量对支架承载能力的影响，并通过实验室试验研究得出拱形金属支架实施壁后充填后，充填层与支架的联合承载特征，从而进一步说明了支架壁后充填的作用。The load-beafing capacity of arched metal support is largely related to the condition of its applied load. The improvement of loading condition is favorable to fully develop the load-bearing capacity of support. The implementation of backfilling is an effectivemethod to improve the loading condition of support.Based on the analysis of the influenceof backfilling and its quality on the load-bearing capacity, the combined loading feature ofsupport and filling layer after implementation of backfilling have been obtained throughthe laboratory study. Therefore, the functions of backfilling are illustrated further.
