广州港新沙二期工程挖入式港池驳船码头结构方案比选分析

Analysis on Structural Schemes of Barge Berth for Dredged Harbor Basins in Guangzhou Port Xinsha Second Phase Project

广州港新沙二期工程的驳船码头采用挖入式港池的平面布置形态,解决了集装箱驳船和散粮驳船的泊位紧缺难题,完善了集疏运体系,节约了深水岸线。针对工程区域复杂的地质条件,从施工、造价、工期、质量等方面对驳船码头结构方案进行论证,对斜撑板桩方案、重力式沉箱方案、单锚钢管板桩等方案进行比较分析,确定了合理的水工方案,总结了钢管板桩的特点,可为类似工程设计提供参考。

The barge berth in Guangzhou port xinsha second phase project adapts the dock layout form of dredged harbor basins, which solves the problem of the shortage of container bargesr and bulk grain bargesr berth, improves the col-lecting and distributing system and saves deepwater coastline. Aiming at the complexity of engineering regional geological conditions, structural schemes of barge berth are demonstrated from some aspects such as construction, cost, schedule and quality. By the comparative analysis on some schemes such as the diagonal bracing sheet-pile scheme, gravity caisson scheme and single-anchor steel sheet-pile, the reasonable hydraulic scheme is confirmed, and characteristics of the steel sheet-pile are summarized, which provides a reference for similar engineering designs.
