摘要
结合杭州湾跨海大桥的桩基施工,介绍在水深浪大的海面环境下,采用打桩船锤击钢管桩的沉桩施工工艺,以及“海上打桩GPS-RTK定位系统”在沉桩测量中的具体应用。钢管桩均为超长大直径斜桩,施工难度极大,其施工经验值得推广应用。
With reference to the construction of pile foundations of Hangzhou Bay Bridge, this paper presents the construction technology for driving of steel pipe piles with floating pile drivers at sea where water is deep and waves are violent, and specific application of the GPS-RTK Positioning System for Pile Driving at Sea to the measurement of the driven piles. The piles in question are all of very long and large diameter batter piles, the construction of these piles is extremely difficult, and construction experiences thereof are worthy of popularization.
