摘要
主要针对护盾式TBM法施工隧洞掘进过程中发生的"洞抱盾"问题进行研究,分析了围岩变形等因素造成TBM抱盾的成生机制,提出了预测方法与风险评估思路,用于前期勘察设计阶段的TBM抱盾卡机预测和评价.
Abstract
This paper mainly focuses on the problem of"shield gripping"that occurs during the tunnel excavation process using the shielded Tunnel Boring Machine(TBM).It analyzes the generation mechanism of shield gripping caused by factors such as rock deformation,and proposes a prediction method and risk assessment approach for shield gripping and jamming in the preliminary investigation and design stages.
