土压平衡盾构复合式刀盘设计与结构有限元分析

Compound Cutter-head Design and Structure Finite Element Analysis for Earth Pressure Balance Shield

简要介绍了土压平衡盾构复合式刀盘适应的地层;重点论述了刀盘的结构设计、刀具配置与布局特点,建立了刀盘主体结构的有限元分析模型;对盾构刀盘在模拟载荷作用下的结构响应进行了数值分析,分析结果符合设计预期。

The applicable geology for compound cutter-head for earth pressure balance shiled is introduced briefly; this pa-per gives discussion about the characters of cutter-head structure design, cutter configuration and position, and constructs the FEM model for cutter-head main structure; The structure response of cutter-head under stimulated load was computed numerically and analysis result is consistent with assumed design.
