洋山港三期驳岸回填施工及位移影响分析

Analysis on backfill construction and displacement effects of the revetment phase Ⅲ Yangshan Port project

洋山港水工码头驳岸工程包括承台结构、承台后方的挡土墙、抛石棱体及内侧倒滤层结构。施工期存在因软土层上回填过高过快失控导致承台和码头位移过大的教训,也存在在回填区范围内监测控制点不稳定、工程协调和控制欠缺等问题。通过采取相应的技术和管理措施,驳岸结构质量控制良好。

Yangshan Port hydraulic wharf revetment project includes caps structure, retaining walls behind caps, riprap mound and inner inverted filter structure. The backfill on soft soil layer during construction is too high and fast to get out of control resulting in the displacements of caps and wharfs are too large, it has the problems that the monitoring and control point in the backfill area is instability and the coordination and control of engineering is lacked. By taking appropriate technology and management measures, the revetment structure quality control is good.
