摘　　要：针对深圳市春风隧道盾构施工中要穿越复杂地质及各种建构筑物的风险因素,利用层次分析法,对春风隧道施工进行风险源权重评价。在评价过程中,建立了隧道施工风险评价指标体系,运用判断矩阵计算出隧道中各因素的影响权重,根据权重大小进行比较,从而确定影响隧道施工的主要风险源。结果表明,在盾构施工中,盾构轴线偏移、建构筑物出现裂隙或破坏、盾构选型、开挖面失稳等危险有害因素对其影响较大,针对各项风险源提出了具体的管控措施,保证盾构隧道施工的安全。In view of the risk factors of complex geology and various structures in the shield construction of Shenzhen Spring Wind Tunnel,the analytic hierarchy process is used to evaluate the tunnel construction risk reasonably and scientifically.In the evaluation process,the tunnel construction risk evaluation index system is established.The influence weight of each factor in the tunnel construction is determined by calculating the judgment matrix,and the main factors affecting the tunnel construction are found out.The results show that in the shield tunnel construction of the spring breeze,the shield axis offset,the cracks or damage of the structure,the shield selection,the instability of the excavation surface and other dangerous and harmful factors have a great impact on it and some corresponding safety control measures are put forward for different risk factors to ensure safe and smooth tunnel construction.
