摘要
结合上海越江隧道工程,选取滚沙、下卧土层液化、不均匀沉降为纵向变形影响因素,运用等效轴向刚度连续模型,进行隧道纵向受力分析,以此分析盾构隧道的破坏机理,并提出安全性建议。
Combined with cross-river tunnel project in Shanghai, the article introducers the factors caused longitudinal deformation from the selection of rolling sand, liquefaction of underlying stratum and uneven settlement, and carries out longitudinal loaded analysis of the tunnel using continuous model with equivalent axial rigidity, analyzes the failure mechanism of shield tunnel , and makes rome safety suggestions.
