摘要
为了预防和控制地铁施工塌方事故的发生,对塌方原因进行研究,基于集对分析的综合评价方法,对相应的集对联系度进行定义,并确定联系数,最终确定了导致地铁隧道塌方的6类主要因素,建立地铁工程塌方风险初步评价指标,并经过工程实例得到权重指标和联系数确定各因素风险大小。结果表明:基于集对分析的综合评价方法能够从人为、勘察设计、施工技术、施工环境、施工管理5方面识别出可能造成塌方的14个风险因素,并确定出施工项目中的最大的风险因素,方便管理者提出相应的应对方案,使塌方风险降到最低。
In order to prevent and control the collapse accidents that happen in subway tunnel construction,the causes of the collapses were studied;based on set pair analysis,corresponding set pair connection was defined,and six principal factors that cause the collapses were determined.Indicators for preliminary evaluation of collapse risk were established,and weight index and connection number were found in practical projects to be the indicators of risk.Results show that 14 factors will be indentified by the comprehensive evaluation measure based on set pair analysis,including the one that causes the biggest risk.
