摘要
利用模糊层次综合评判方法建立西安地铁1号线地铁半坡—纺织城区间特殊地质情况施工评估分析模型,并利用该模型对地铁施工安全影响较大的风险因素湿陷性黄土和地裂缝进行分析评估,得出其危险事件发生的概率和各基本事件的重要度,针对计算风险等级系数制定该工程事故的技术预防措施。根据地铁隧道工程项目自身特点,对风险进行控制和管理。
Fuzzy comprehensive evaluation method is used to establish the model of Metro Line 1 Xi＇an Banpo--Textile zone subway construction assessment with special geological conditions. Collapsible loess and ground fissures are security risk factors and have significant impact on construction of the subway. So we have an assessment of them, get the probability of occurrence about dangerous events and the importance of basic events, formulate project prevention measures of accident in accordance with risk rating coefficient. Realize risk control and management in accordance with subway tunnel project＇s own characteristics.
