摘　　要：施工风险包括自身风险和环境风险两种。将城市地铁小盾构施工所面临的环境风险作为研究的对象,根据国家风险等级及控制标准,对案例工程盾构施工区域内风险源进行了识别,并确定了风险源的风险等级。通过有限元数值模型对各风险源进行了沉降和水平变形模拟分析,提出了可行的控制措施,对本工程盾构施工起到了指导性的作用。Construction risks include self-risk and environmental risk.This paper takes the environmental risks faced by subway shield construction as the research object,and identifies the risk sources in the shield construction area according to national risk levels and control standards,and determines the risk levels of the risk sources.The finite element numerical model was used to simulate the settlement and horizontal deformation of each risk source,and proposed feasible control measures,which played a guiding role in the shield construction of this project.

关 键 词：盾构施工 风险源 控制措施
