摘要
针对台山核电站海底隧道泥水平衡盾构施工中要穿越不良地质体及地层结构界面的风险因素,利用模糊层次分析法对其进行辨识、分析、评价.结果表明在海底隧道盾构施工中,废弃物、孤石充填物力学指标不详、渗漏、换刀影响工期等危险有害因素对其影响较大,针对风险问题提出了有针对性的安全控制措施,保证了海底隧道安全顺利施工.
There are a lot of risks in construction of tunnel of Taishan nuclear power crossing the bad geological body and stratigraphic structure interface. The key problems of risks of tunnel construction is to identify, analyze, evaluate and take measures. This paper calculated quantitatively of risk factors with analytic hierarchy process according to the construction characteristics of Taishan nuclear power tunnel. The MATLAB software was used in calculating for each risk factor relative to the overall goal of diversion tunnel construction risk assessment sorting weight. Through evaluation of risks of different construction phase, the safety of tunnel construction was ensured by adopting corresponding control measures.
