中文摘要：

为实现对地铁施工系统风险的动态分析，运用基于集对分析的五元联系数风险综合评价模型，建立地铁施工系统的风险综合评价体系。利用该风险综合评价体系，综合评价某段地铁施工项目的风险，并分析其风险态势以及风险发展趋势。结果表明，该风险综合评价体系可以避免传统评价方法不能对风险趋势做出合理预测的缺点，能够定量表达复杂系统的决策思维，在实际应用中具有可操作性，使风险评价结果更加科学合理。

英文摘要：

For the purpose of making dynamic analysis of risks involved with subway construction sys- tem, according to five-element connection number comprehensive evaluation model of risk which based on set pair analysis, a comprehensive evaluation system of risks involved with subway construction was built. This system was applied to making comprehensive evaluation of risks involved with a certain subway con- struction project, and analyzing the situation and development trend of the risks. The results show that the comprehensive evaluation system avoids the disadvantages of the traditional evaluation method which can＇t make a reasonable prediction of the trend of risk, that it can express quantitatively decision thinking of a complex system, and that it is more operable in practice, and the evaluation results are more scientific and reasonable.
