基于联系数的地铁隧道施工邻近建筑物风险评价

Risk Assessment of neighboring building in Metro Tunneling Construction Based on Connection Number

在全面分析邻近建筑物风险影响因素的基础上,把集对分析原理应用于风险评价中,提出了一种新的基于集对分析的联系数风险评价模型。该模型构建了风险因子与评价标准之间的联系数,结合因素权重评价了建筑物的风险等级,通过集对势与偏联系数综合评判了风险的发展趋势,并对建筑物风险发展趋势进行了排序。该方法集风险状态评价与发展趋势分析于一体,可为地铁邻近建筑物的风险管理提供理论参考。

The risk factors of adjacent buildings should be firstly comprehensive analyzed. The set pair analysis is employed in the risk assessment and a new connection number assessment medel of risk is proposed. ＇I＇nis model constructs the connect number between risk factors and assessment criteria. The risk level of the building is evaluated combined with the weight of factors, the devdoping trend of the risk is comprehensively assessed by set pair potential and partial connection number and al- so the developing trend of the risks is sorted. The method synthesizes risk status and analysis of developing trend for the risk and it can provide theoretical references for the risk management of metro adjacent buildings.
