[摘要] 在我国的各类矿山以及矿山相关企业中，存在着大量的钢筋混凝土结构。这些结构大部分长期承受小能量、高频次的冲击、磨损以及化学腐蚀等作用，导致其迅速失效，进而导致矿山企业产量下降，维修安全性降低。本文以试验为基础，研究了冲击速度与钢筋混凝土结构磨损量的关系，得出了钢筋混凝土结构的冲击磨损量与磨料的动量成正比的结论，确定了相关系数。为今后矿山中此类钢筋混凝土结构的设计、施工等方面工作提供相应的依据。

Abstract: There are lots of reinforced concrete structures in mining area. Under the collision of little amount of energy, great frequency, attrition wear and chemical denudation, the reinforced concrete structure will inactivate quickly. It lead to the volume of production fall down and maintenance exposure increase. In the paper, on the base of test the relation of velocity and wearing capacity was studied. It proved that reinforced concrete structure wearing capacity direct ratio to abradant momentum and the coefficient of association was determined. These achievements supply corresponding experience for design and execution ofreinforced concrete structure.
Keywords: reinforced concrete structure; attack wear; momentum; wearing amount; coefficient of association
