孟加拉卡纳普里河底隧道工程盾构段为双线公路隧道，采用“一机双隧”掘进模式，左线接收段处在滨海地区强透水粉细砂地层，采用常规的盾构接收工艺时极易造成涌沙涌水而导致盾构接收失败。为确保盾构安全高效接收，也为了衔接盾构接收后平移转体再始发的施工工艺，采用钢套筒接收工艺，同时针对该施工技术的较大风险点进行预判并制定相应防控及应急措施，保证大直径泥水盾构钢套筒接收的顺利实施。孟加拉隧道施工现场不断优化大直径泥水平衡盾构接收工艺，从套筒设计和变形防控、工作井端头加固、洞门凿除、盾构进洞施工监测、掘进参数控制、洞门封堵和进洞段管片稳定性控制等方面进行理论分析、模拟试验和工法优化，最终形成一套滨海地区富水砂层大直径泥水平衡盾构钢套筒接收的关键施工技术。

The shield section of the Karnaphuli Rivercrossing tunnel project in Bangladesh is a doubletube highway tunnel, and both the tunnels are bored using the same shield. The shieldreceiving section of the left line is located in a highlypermeable siltyfine sand strata in coastal area where in conventional shield receiving technology would easily cause sand and water gushing, leading to the failure of shield receiving. Accordingly, to ensure safe and efficient shield receiving and realize secondary launching, steelsleeve receiving technology is adopted. Furthermore, the major risk points of the construction technology are predicted to determine the corresponding prevention and control and emergency 〖HJ2mm〗measures, thus ensuring smooth implementation of largediameter slurry shield steelsleeve receiving. The largediameter 〖ＨＪ2.3mm〗slurry balance shieldreceiving process has been continuously optimized at the tunnel construction site in Bangladesh, and theoretical analysis, simulation test, and method optimization are conducted regarding the sleeve design, deformation control, shaft end reinforcement, portal cutting, shield tunneling monitoring, construction parameter control, portal sealing, and segment stability control at the receiving section. Eventually, key construction technologies for the steelsleeve receiving of a largediameter slurry balance shield suitable for waterrich siltyfine sand strata in coastal areas are formed.
