浅析TBM隧道管片的结构设计

摘要

In light of fabricated segment construction characteristics in TBM tunnel masonry,it describes the general principle and loading mode of TBM tunnel fabricated segment structure design by applying optimum theory,and shows suggestions for segment calculatio%针对TBM隧道衬砌中所用预制管片的施工特点,运用优化的理论阐述了TBM隧道预制管片结构设计的一般原则和荷载模式,并且结合工程实例给出了管片计算模型选择的建议,以期指导实践。
