摘要:
为探明内径1 600 mm大直径钢筋钢筒混凝土排水管在回填施工时的承载性能，依托雄安新区起步区市政排水工程，采用现场原型试验、数值模拟及现场监测的方法研究大直径钢筋钢筒混凝土排水管的外压承载性能。研究结果表明：大直径钢筋钢筒混凝土排水管在外压作用下应变响应根据变化的特征分为弹性阶段、塑性阶段及开裂破坏阶段；现场原型试验结果表明该排水管的外压承载性能满足设计需求；随回填施工的进行，管中各结构的力学响应基本协同一致；现场监测与数值计算结果规律基本一致，各项监测指标均在结构承载能力范围内，验证大直径钢筋钢筒混凝土管现场应用的安全性。研究结果可为类似的大直径钢筋钢筒混凝土排水管的设计与施工提供参考。
Abstract:
In order to clarify the bearing performance of a large-diameter reinforced steel-cylinder concrete drainage pipe with an inner diameter of 1 600 mm during backfilling,this study relies on a municipal drainage project in the startup area of Xiong’an New Area and investigates the external pressure capacity of the pipe through field prototype tests,numerical simulation,and on-site monitoring.The results show that,under external pressure,the strain response of the pipe can be categorized into an elastic stage,a plastic stage,and a cracking failure stage according to its evolution characteristics.The field prototype tests indicate that the external pressure capacity of the pipe satisfies the design requirements.As the backfilling proceeds,the mechanical responses of the structural components inside the pipe remain essentially coordinated and consistent.The trends from on-site monitoring agree well with those from numerical calculations,and all monitored indicators stay within the structural bearing capacity,which verifies the safety of field application for this type of large-diameter reinforced steel-cylinder concrete pipe.These findings provide a reference for the design and construction of similar large-diameter reinforced steel-cylinder concrete drainage pipes.
