| 摘 要： | 结合杭州湾跨海大桥北航道桥栈桥工程实践,在打桩船未安装商用海上GPS打桩定位系统的条件下,本文提出了一种新的利用常规仪器完成海上桩基钢管桩的插打测量定位方法,并实现了快速准确地对钢管桩的插打测量定位。通过对沉桩进行的偏位检查表明,该方法完全能够满足钢管桩测量定位的精度和配合施工作业的进度。

| Abstract: | Through the construction practice of the trestle over the north principal channel of Hangzhou Gulf Bridge, under the condition of a pile driving barge without equipments of the commercial GPS positioning system for offshore pile driving, a new method of marine driving positioned by the use of normal surveying instruments is presented, and the rapid and accurate survey for positioning steel-pipe piles achieved. By the check to the deviation of driven piles, it indicates that the method can completely meet the precision of surveying positioning to steel-pipe piles and can coordinate the progress of construction work. |
