%X 盾构法作为地铁施工的专项工程技术，被越来越多的工程建设单位所选择。因此，本文介绍了国内外盾构机，盾构机的分类和选用原则。无水砂卵石地层是典型的力学不稳定地层，其颗粒间的胶结能力极差，离散性强。基于此，分析了无水砂卵石地层盾构机选型的风险，提出相应的建议，以加强对此类地层盾构机选型的认识。<br />
As a special engineering technology of subway construction, shield method is selected by more and more engineering construction units. Therefore, this paper introduces the development history of shield machine at home and abroad, and the classification and selection principle of shield machine. Anhydrous sandy pebble stratum is a typical mechanically unstable stratum with poor cementation ability and strong dispersion between particles. Based on this, the risk of shield machine selection in anhydrous sandy pebble stratum is analyzed, and the corresponding suggestions are put forward, so as to strengthen the understanding of shield machine selection in this kind of stratum.
