摘　　要：随着城市建设现代化水平的提高,许多城市采用盾构施工方法来建设综合管廊。传统的事故树分析方法无法解决现代化城市综合管廊建设施工风险的复杂性问题。以管廊盾构施工导致的地面沉降事故为例,采用层次分析方法建立管廊盾构施工的动态事故树(DFT),并定性分析得出工程材料合格性、管片规格匹配性、采取相应的补救措施对管廊盾构施工导致地面沉降事故的影响程度较大,同时通过案例分析证明了采用DFT来分析城市综合管廊盾构施工过程中的危险因素具有可行性,可为城市综合管廊施工风险分析与评价提供新的思路。With the improvement of the modernization level of urban construction,the method of shield construction has been adopted in many cities for urban integrated pipe gallery construction.Traditional fault tree is unable to effectively address the complexity of the risks of integrated pipe gallery construction of modern cities.Therefore,this paper takes the ground subsidence incident resulted from pipe gallery shield construction as an example,and establishes a Dynamic Fault Tree(DFT)for shield construction of integrated pipe gallery using the Analytic Hierarchy Process.Results show that the engineering materials qualification,segment specification matching,and the corresponding remedial measures have great influence on the ground subsidence incident caused by shield construction of pipe gallery.Moreover,the feasibility of applying DFT analysis to tunnel shield construction accidents has been proved by the case study,and it provides some ideas and methods for risk analysis and assessment of shield construction of urban integrated pipe gallery.
