天津津滨轻轨西段工程盾构隧道施工风险管理

摘要

In the engineering practice, more attentions have been paid to the risk accidents during the tunneling. How to reduce the risk accidents and the following losses have become an important topic. In this paper,a general risk assessment process of tunneling engineering is proposed to the project of Taijin-Binhai metro west segment, the risk accidents during construction are identified through expert investigation method and AHP method, then the fuzzy synthesis evaluation is used in risk assessment,some suggestions about risk control measures are presented.%最大程度降低盾构隧道施工中的风险事故发生率以及事故造成的损失,是工程实际中迫切需要解决的一个难题.根据风险分析流程,结合天津津滨轻轨西段工程七经路至天津站站区间盾构隧道实例,对该工程的主要风险,首先采用专家调查法和层次分析法进行了识别,然后应用模糊综合评判对盾构穿越铁路股道的施工风险进行了统计、计算和综合分析评估.提出了天津津滨轻轨工程盾构隧道施工的风险控制措施.
