摘　　要：相关标准中规定的6 d长度钢丝绳允许可见断丝数与30 d长度钢丝绳的允许可见断丝数之比并不等于长度比。采用概率论和可靠性分析,证明了30 d长度钢丝绳的允许可见断丝数,保证了钢丝绳的运行安全。交互捻钢丝绳与同向捻钢丝绳30 d长度的允许可见断丝数之比为2∶1,但最小可靠度相同。The ratio of allowable visible broken wire number in wire rope which length is 6 d and 30 d specified in relevant standard is not the same.Based on probability theory and reliability analysis,it is proved that the number of visible broken wire in wire rope which length 30 d ensures the safety condition of wire rope.The ratio of visible broken wire number in ordinary lay and lang lay is 2∶1,however,they both have the same minimum reliability.
