摘　　要：港口门座起重机作为港口装却作业的特种设备,在港口码头装卸作业发挥了重要作用,在役的门座起重机存在着设备老龄化、受力状态复杂、工作环境恶劣等诸多问题,受到了各方的密切关注。本文对门座起重机风险评价技术理论进行深入的研究,综合比较各种风险评价方法并借鉴现阶段风险评价理论成果,运用基于风险的检验技术(RBI)的原理,将门座起重机的风险定义为失效可能性和失效后果严重性的综合,确定将灰色模糊综合评价法作为门座起重机风险评价的方法并建立风险评价模型。As a key port handling equipment,portal crane is playing an important role in port handling work.With the aging of the portal crane,the complex stress state coming with harsh working conditions,the safety problem of the portal crane becomes more prominent.In this paper,the theory of risk assessment technology of portal crane is studied,then various of risk evaluation methods and reference results are compared.Based on the principle of the Risk-Based Inspection(RBI),the risk of portal crane is defined as the comprehensive effects of failure probability and severity of consequences.The grey fuzzy comprehensive evaluation method is chosed as the portal crane risk assessment method.
