摘　　要：针对隧道区域的岩土情况、复杂的地质条件、纵断面形状、双线隧道净距小、埋深变化大和水压大等问题,以长江小断面大陡坡越江输气隧道项目为例,系统分析影响隧道选线与施工方法的多种因素。基于层次分析法构建决策指标体系,综合运用标度法和专家权重系数法确定指标权重,采用改进模糊层次分析法进行评价与比较研究。结果表明,优化后的路线与实际选取路线基本一致,该决策模型克服传统模型单一性和主观性,具有实用性和合理性,为隧道选线与施工方法决策提供有益参考。In view of the geotechnical conditions,complex geological conditions,longitudinal section shape,small net distance of double-lane tunnel,large change in buried depth and large water pressure in the tunnel area,taking the Yangtze River small section steep slope cross river gas transmission tunnel project as an example,a variety of factors affecting the tunnel route selection and construction method were systematically analyzed.Based on the Analytic Hierarchy Process(AHP),a decision indicator system was constructed,and the weights of the indicators were determined comprehensively using the scaling method and expert weight coefficient method.The improved Fuzzy Analytic Hierarchy Process was used for evaluation and comparison.The results showed that the optimized route was basically consistent with the actual selected route.This decision model overcame the singularity and subjectivity of traditional models,had practicality and rationality,and provided useful references for tunnel route selection and construction method decision-making.
