基于模糊数学理论探讨评判地铁工程中地下水风险

Groundwater Risk Assessment of Metro Project Based on Fuzzy Mathematical Method

摘要:

采用模糊综合评价法,以上海地铁10号线南京东路车站为例,在全面识别勘察、设计、施工和运营过程中地下水风险因子的基础上,结合统计资料和专家评价,详细阐述了风险评估模型的建立及评价过程,得到了不同阶段地下水风险因子的权重,并对地下水风险进行了综合评判.研究结果对上海地铁工程地下水风险控制具有指导意义.

Abstract:

Fuzzy comprehensive evaluation method is used to do the groundwater risk assessment of East Nanjing Road Station of Metro Line 10 in Shanghai.Meanwhile,the establishment of risk assessment model and evaluation process is described in detail based on the comprehensive identification of groundwater risk factors during the process of investigation,design,construction and operation,combining with the analysis of project information and expert evaluation.Weights of groundwater risk factors are obtained,as well as a comprehensive evaluation on the groundwater risk.The research conclusion may provide a technical guidance for the groundwater risk analysis of metro projects in Shanghai.
