摘要
盾构接收作为盾构施工过程中的关键风险环节,其技术选择对工程安全与经济效益具有显著影响。基于南京地铁三个车站的盾构接收案例,对比分析了传统“现浇混凝土挡墙”工法、“钢套筒”工法以及新兴的“装配式钢板箱”工法。通过适用条件、安全性能、施工工效、施工成本四个维度的综合评估,研究发现“装配式钢板箱”技术在盾构水中接收环节展现出显著的应用优势,特别是在应急抢险场景下的应用潜力,旨在为类似工程条件下的盾构接收技术选择提供理论依据。
Shield tunneling reception is a critical risk element in the shield construction process,and the choice of technology significantly impacts the safety and economic benefits of the project.This study,based on the shield tunneling reception cases of three Nanjing subway stations,compares and analyzes the traditional“cast-in-place concrete diaphragm wall”method,the“steel sleeve”method,and the emerging“prefabricated steel plate box”method.Through a comprehensive assessment from four dimensions:applicable conditions,safety performance,construction efficiency,and construction cost,the study finds that the“prefabricated steel plate box”technology shows significant advantages in the shield tunneling reception process,especially in emergency rescue scenarios.This paper aims to provide a theoretical basis and practical guidance for the selection of shield tunneling reception technology under similar engineering conditions.
