摘要/Abstract

摘要： 为确定高水压饱和砂层盾构地中对接的最优结构方案，以江阴靖江长江隧道工程为背景，选取超高性能混凝土（UHPC）、现浇钢筋混凝土和钢壳混凝土3种对接段结构方案分别进行研究。首先，通过建立有限元模型分别分析3种对接段结构的运营期安全性，并探讨结构的施工可行性和具体施工流程；然后，从承载能力、施工可行性、经济性、工期、耐久性及防火性能等多维度对3种对接段结构进行综合比选，最终优选钢壳混凝土为对接段结构；最后，对该结构在对接施工过程中的力学响应进行实时监测和分析。研究结果表明： 1）3种方案均能满足运营期承载力和施工可行性要求； 2）钢壳混凝土方案在快速成环、综合成本控制（造价比其他方案低28%以上）等方面优势突出，且满足高水压饱和砂层中盾构对接段“快速封闭、抗渗防涌、短期承载”的特殊技术要求，其在耐久性、防火性能等方面的固有劣势可通过涂刷防腐涂料、增设防火板等技术措施弥补； 3）基于对接段结构施工过程的监测数据显示，盾体实际沉降量仅7.7 mm，为设计限值150 mm的5.1%，结构最大应力增量为26.5 MPa，未超过规范限值，验证了钢壳混凝土对接结构的安全性与可靠性。

Abstract: To determine the optimal structural scheme for underground shield docking in high-water-pressure saturated sandy stratum, a case study is conducted on the Jiangyin-Jingjiang Yangtze River Tunnel Project, and three structural schemes—ultra-high-performance concrete, cast-in-place reinforced concrete，and steel-shell concrete—are evaluated. First, finite element models were established to analyze the operational safety of each scheme, followed by a discussion of their construction feasibility and detailed processes. Second, a comprehensive comparison was conducted based on bearing capacity, construction feasibility, economic performance, construction period, durability, and fire resistance. The steel-shell concrete scheme was identified as the optimal docking structure. Finally, the mechanical response of this structure during docking construction was monitored and analyzed in real time. The research yielded the following key findings: (1) All three schemes meet the bearing capacity requirements for operation and demonstrate construction feasibility. (2) The steel-shell concrete scheme offers significant advantages in rapid ring formation and overall cost control, with construction costs more than 28% lower than the other two schemes. This scheme effectively addresses the unique technical requirements of “rapid closure, impermeability and water inrush prevention, and short-term load-bearing” essential for shield docking structures in high-water-pressure saturated sandy stratum. Its inherent limitations in durability and fire resistance can be mitigated by applying anti-corrosion coatings and installing fireproof panels. (3) Field monitoring data collected during construction indicate that the actual shield settlement is only 7.7 mm, representing 5.1% of the design limit of 150 mm. The maximum stress increment within the structure reaches 26.5 MPa, remaining below the code-specified limit. These results confirm the safety and reliability of the steel-shell concrete docking structure.
