深水超长沉管隧道接头及止水带地震响应
|
摘要
依托港珠澳沉管隧道工程,建立了3维实体连续有限元模型,对这条深水超长沉管隧道在地震作用时接头处的内力和位移情况以及止水带的压缩与变形进行了详细的模拟与研究,重点分析了地震作用时沉管隧道接头处的相对位移(包括管节接头和节段接头)、管节接头处GINA止水带的变形,为施工和运营期的安全与维护提供必要的指导和依据.
Based on Hong Kong-Zhuhai-Macao Cross-Harbor Tunnel Project,a three-dimensional continuous model is established to research joints' forces and displacements and GINA gaskets' deformation.The study focuses on joints' relative displacement,including pipe joints and segment joints,and GINA gaskets' deformation.There is an important guiding significance for design and construction of immersed tube tunnel.
