(遼寧工程技術(shù)大學(xué)土木與交通學(xué)院，阜新123000)[摘要] 在我國的各類礦山以及礦山相關(guān)企業(yè)中，存在著大量的鋼筋混凝土結(jié)構(gòu)。這些結(jié)構(gòu)大部分長期承受小能量、高頻次的沖擊、磨損以及化學(xué)腐蝕等作用，導(dǎo)致其迅速失效，進(jìn)而導(dǎo)致礦山企業(yè)產(chǎn)量下降，維修安全性降低。本文以試驗為基礎(chǔ)，研究了沖擊速度與鋼筋混凝土結(jié)構(gòu)磨損量的關(guān)系，得出了鋼筋混凝土結(jié)構(gòu)的沖擊磨損量與磨料的動量成正比的結(jié)論，確定了相關(guān)系數(shù)。為今后礦山中此類鋼筋混凝土結(jié)構(gòu)的設(shè)計、施工等方面工作提供相應(yīng)的依據(jù)。

(Liaoning Engineering and Technology University, Fuxin 123000, China)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
