Based on the geological and hydrological conditions of a certain river-crossing tunnel project,combined with the char-acteristics of large cross-section,long distance,and high water pressure between the proposed project,the major and difficult points of shield construction in the composite stratum with uneven soft and hard are discussed.Based on the corresponding theoreti-cal research results and typical application cases,it focuses on the targeted design and analysis of the cutter head structure,cutter configuration,center erosion,etc.of the proposed super large-diameter shield machine,with the aim of designing a design that matches the construction of the proposed tunnel.The shield cutter head solves the construction difficulties faced by the proposed sec-tion,avoids construction risks,and provides a certain reference for the subsequent shield cutter head design of similar projects.
