【摘要】 目前，煤矿中大量钢桁架结构通廊均存在不同程度的耐久性损伤，这些损伤影响着通廊的结构安全。如何通过安全排查掌握通廊完损状况、发现结构安全隐患是一个亟待解决的问题。为此，采用传力树概念，分析通廊结构体系，通过模糊综合评判法，得出了能够客观反映钢桁架结构通廊完损状况的排查结论。更多还原

【Abstract】 At present, a large number of steel truss corridors in coal mines have different degrees of durability damage, which affect the structural safety of corridors. It is an urgent problem that how to grasp the damage condition of the corridor and find the hidden danger of structural safety through safety inspection method. Therefore, the concept of force transfer tree is used to analyze the corridor structure system. Through the fuzzy comprehensive evaluation method, the inspection conclusion is obtained in order to objectively reflect the damage condition of the steel truss corridors.更多还原
