地铁盾构施工过程及其风险评估研究

On construction process of subway shield and its risk evaluation

依据地铁盾构施工的特点和分类,将地铁盾构施工技术与传统的矿山法进行了对比,介绍了地铁盾构施工技术的优点和流程,并结合盾构施工风险的定义,探讨了地铁施工风险发生的机理,为构建地铁盾构施工风险评价指标体系提供了依据。

According to the features and classification of the subway shield construction, compares the subway shield technique with the tradition-al mining method, introduces its advantages and procedure, and explores the risk occurrence principle for the subway construction combining with the definition of the shield construction risks, so as to provide some reference for the risk evaluation indexes of the subway shield construction.
