摘　　要：利用熵权法和模糊综合评价法相结合的方法,建立公路隧道竖井开挖施工方案的模糊综合评价模型,实现公路隧道竖井开挖施工方案的有效评估和排序。该方法根据决策专家的意见,建立模糊综合评价矩阵,并通过熵权法确定各因素的权重系数,实现专家意见的主观性和熵权法客观性的结合。最终计算得到模糊综合评价结果,对方案进行排序并确定最优方案。以十房高速公路通省隧道竖井开挖为例,运用该模型对钻爆法、爬罐法、吊罐法、钻孔反井法4种施工方法进行评估,计算结果表明:钻孔反井法最优。工程实践表明,钻孔反井法合理有效,验证了该评价模型的有效性。Based on entropy-weight method and fuzzy comprehensive evaluation method, a fuzzy comprehensive evaluation model for highway tunnel shaft excavation construction schemes is established.By using this model, the effective evaluation and ranking of the excavation construction schemes of the highway tunnel shaft is accomplished. The fuzzy comprehensive evaluation matrix is built according to the opinions of the experts. The weight coefficient of each factor is also determined by the entropy-weight method. The combination of the subjectivity of expert opinion and the objectivity of entropy-weight method is achieved. Finally, the schemes are sorted according to the fuzzy comprehensive evaluation results. The proposed method is applied to the shaft construction of Tongsheng tunnel of Shifang highway. By using the model, drilling and blasting method, climbing method, cage raising method and drilling anti-well method are assessed. The calculation result shows that drilling anti-well method is the best. The engineering practice shows that drilling anti-well method is reasonable and effective, and supports the validity of the assessment model.
