曹妃甸通用码头二期工程沉降位移观测分析

Settlement and displacement observation of Caofeidian universal terminal phase Ⅱ engineering

曹妃甸通用码头二期工程采用沉箱重力式结构,抛石基床施工时分别采用分层夯实和一次爆夯的方式,该结构和施工方法在曹妃甸港区码头中系首次。工程实施过程中对码头在施工期各阶段的沉降、位移进行了全面观测,对获取的数据进行了细致分析,对类似工程施工具有借鉴意义。

Caofeidian universal terminal phase II engineering adopts the caisson gravity structure,and the rubble bed construction employs hierarchical compaction and blasting ramming,which were applied for the first time in Caofeidian quays.Comprehensive observations of settlement and displacement at various stages are executed in the construction process.The analysis of the data adopted may serve as a reference for similar projects.
