摘要
某跨海大桥主体结构为2×230 m双索面独塔斜拉桥,采用钢管复合桩群桩基础,单桩为直径4.3 m钻孔灌注桩,按嵌岩桩设计。现着重介绍其大直径钢管复合桩施工技术,以及成桩后的桩身完整性检测,以期为同类型工程提供参考和借鉴。
The main structure of a sea crossing bridge is a 2×230 m double-plane single-pylon cable-stayed bridge with the steel pipe composite pile group foundation. The single pile is the diameter 4.3 m of cast-insitu pile, and is designed on the socketed pile. The article focuses introduction on the construction technology of large-diameter steel pipe composite pile and the detection of pile body integrality after the pile completion in order to provide the reference for the similar projects.
