摘　　要：近年来盾构设备的自动化程度越来越高,其适用性得以拓展,能够适用于多种地质条件和复杂环境条件。同时,盾构隧道相对于常规钻爆法暗挖隧道而言,造价水平较高。本文通过对不同直径、不同平衡模式、穿越不同地层盾构隧道的技术经济指标差异分析,对于盾构隧道项目前期方案比选、项目决策、设计阶段合理控制投资提供参考。In recent years,the degree of automation of shield equipment has become higher and higher,and its applicability has been expanded,and it can be applied to a variety of geological conditions and complex environmental conditions.At the same time,the cost of shield tunnels is higher than that of conventional drill-and-blast tunnels.Through the analysis of the differences in the technical and economic indicators of shield tunnels with different diameters,different balance modes and through different strata,this paper provides a reference for the comparison and selection of early schemes,project decision-making and reasonable control of investment in the design stage of shield tunnel projects.
