摘　　要：文章在详细介绍风险理论的基础上,以合肥地铁3号线望江西路车站基坑施工为工程实例,建立了非线性模糊综合评价模型,对该工程进行了单因素风险评价、分级模糊综合评价等,确定了其总体风险等级为四级,最后将理论与实际相结合,针对基坑的变形控制,提出了意见和建议。该研究对相关工程的风险评价体系有一定的充实,对相关工程的风险评价有一定的参考意义。Based on the detailed introduction of risk theory,in view of the foundation pit construction of Wangjiang West Road Station of Hefei Metro Line 3,a nonlinear fuzzy comprehensive evaluation model was established.The single factor risk evaluation and hierarchical fuzzy comprehensive evaluation and so on were carried out on the project,and the overall risk level was determined as the fourth level.Finally,on the basis of theoretical analysis and practical application,suggestions were put forward for the deformation control of the foundation pit.This research enriches the risk assessment system of related projects to a certain extent,and has certain reference significance for the risk assessment of related projects.
