地铁隧道暗挖施工是一个非常复杂的不确定系统,为了对其进行有效的风险管理,进行了地铁隧道暗挖施工的风险性评价的研究。首先确定了风险性评价等级和风险接受准则,然后采用问卷调查法确定了风险性评价指标,接着基于模糊数学和层次分析法建立了模糊综合评价模型,最后应用该评价模型对某沿海城市的地铁隧道暗挖施工进行了风险性评价,评价结果与参考文献一致,证实了该评价模型的实用性,从而为风险性评价提供了一种可靠的方法。
Subway tunnel construction is a very complex and uncertain system. In order to carry out effective risk management, the risk assessment of subway tunnel construction is studied. First of all, the level of risk assessment and risk acceptance criteria are determined. Then the risk assessment index is determined by questionnaire survey. Then, a fuzzy comprehensive evaluation model is established based on fuzzy mathematics and analytic hierarchy process. Finally, the evaluation model is applied to a coastal city subway Tunneling excavation carried out a risk assessment, the evaluation results consistent with the references, confirmed the practicality of the evaluation model, thus providing a reliable method for risk assessment.
