| 摘 要： | 地铁深基坑施工技术复杂、不确定因素多,施工阶段发生风险的概率较大且风险损失后果严重.为降低和控制地铁深基坑施工风险,有必要对其进行风险评估.结合工程实例,先根据工程地质条件和施工方法等对主要施工风险进行辨识;然后采用模糊层次分析法得到风险概率等级,并结合专家调查法对风险后果等级进行评估;最后确定地铁深基坑施工风险等级为IV级,并根据主要风险提出了有针对性的施工风险控制措施,确保施工安全.

| Abstract: | Metro deep excavation engineering is characterized by complex construction technology and many unpredictable factors.The risk is likely to occur in construction and bring vast adverse consequence.It is necessary to make a risk assessment to reduce and control the metro deep foundation in construction.In this paper,firstly,according to the geological engineering conditions and construction methods to identify the construction risk through a case study.Secondly,fuzzy analytic hierarchy process is used to determine the risk probability grade;and expert research method is used to assess the risk consequence grade.Thirdly,the risk grade of metro deep excavation in construction is Ⅳ and make specific control measures to ensure the safety according to principal risk in construction. |
