摘　　要：富水粉质黏土地层中,盾构掘进模式的选择是否合理会直接影响盾构掘进效率和地层沉降控制效果。因此,根据泥水平衡盾构和土压平衡盾构掘进特点、隧道穿越的地层特点以及地表沉降控制要求,采用层次分析法建立了盾构掘进模式评价模型,并综合采用专家经验法和工程类比法,确定了模型中各因素的权重;利用该评价模型对泥水平衡模式和土压平衡模式掘进方案进行了评价。研究结果表明,泥水平衡模式和土压平衡模式的综合评判向量分别为[0.573,0.427];根据评价结果可确定盾构掘进模式。In silty clay stratum,the reasonable selection of shield tunneling mode will directly affect the tunneling efficiency and control effect of the stratum settlement.Therefore,according to the characteristics of slurry balance shield tunneling and earth pressure balance shield tunneling,the stratum characteristics of tunnel crossing and the stratum settlement control requirements,an evaluation model of shield tunneling mode is established by analytic hierarchy process(AHP).The weight of each factor in the model is determined by comprehensive adoption of expert experience method and engineering analogy method.The tunneling plan of the slurry balance mode and the earth pressure balance mode are evaluated by the evaluation model.The results show that the comprehensive evaluation vector of the two models are [0.573,0.427] respectively.the shield tunneling mode can be determined according to the evaluation results.
