地铁工程施工安全风险识别规则

Risk Identification Rules for Metro Construction Safety

地铁工程施工安全风险辨识不细致全面、风险控制措施不到位是造成安全事故的原因之一。如何将专家经验和规范中的风险识别知识结构化,通过计算机自动识别风险是应对目前缺乏有经验的风险识别技术人员的良策。而风险识别规则的获取、表示、应用是实现上述目标的关键技术。本文提出地铁工程施工风险识别规则的定义,给出获取风险事件及致险因素构成的步骤,建立致险因素权重、致险因素取值可信度的计算方法,设计了风险识别规则扩展产生式表示、结构化存储的方法,并以武汉地铁二号线螃蟹甲车站工程施工安全风险识别为例,给出了风险识别规则的具体应用。通过总结风险识别规则的内在规律和信息化处理方法,为高效自动识别地铁工程施工安全风险提供技术支撑。

One of the reasons why some accidents occurred is that the metro construction safety risk cannot be meticulously identified and risk control measures are not suitable for the project.How to use risk identification knowledge from expert experiences or construction specifications for the inexperienced engineers,to identify risk automatically by computer is a good idea,and the key technology for this aim is the acquisition,representation,application of risk identification rules.This study defines the concept of risk identification rule,gives steps of risk event and risk factors acquisition,and establishes the calculating methods of risk factors weights and certain factors of risk factor value.The rules for extending production representation and the rules for structuring storage are then proposed.Take the project of Pangxiejia Station on Wuhan Metro Line 2 as an example,the specific application of risk identification rules were given in this study.This paper summarized the inherent laws and the information processing methods about the comprehensive risk identification rules,which provides technical support for metro construction safety risk efficient,automatic identification process.
