| 摘 要： | 深圳港妈湾港区海星码头1#~4#泊位旧码头拆除工程实施过程中,为了防止在原码头深底层保留桩柱对新建桩柱的影响,需要对原码头桩柱泥面以下位置进行精密测量。本文采用船载综合测量系统水上水下一体化测量技术对妈湾港1#~4#泊位桩柱进行了水岸一体化高精度测量,通过利用激光扫描仪和多波束分别测量出水上、水下桩柱引水面点云图。基于高精度水面点云绝对坐标对水上、水下桩柱引水面点云进行特征拼接,从而获得桩柱引水面高精度绝对位置。然后根据引水面绝对位置和桩柱尺寸精准计算出保留桩柱泥面以下部分的点位和斜率。经过外符合精度验证,桩柱定位的绝对精度为10 cm。最后,将旧桩柱测量结果与新桩柱设计结果对比,结果表明：新旧桩柱在2#泊位存在一个桩柱发生碰撞,4#泊位存在10根桩柱新旧桩柱水平间隔小于10 cm,在施工过程中可能会发生碰撞。

| Abstract: | In the process of the demolition of the old pile of Haixing pier in Shenzhen Mawan port, to avoid the remaining pile collide with the on the new pile in the new construction of the wharf, it is necessary to make a precise position of the remaining pile. The position of the remaining pile can be accurately calculated by knowing the point location and the pile slope. In this paper, the ship-borne combined laser and bathymetric surveying technique is used to survey the point location and the pile slope of the remaining pile. We used the laser scanner and multi-beam system to measure the point cloud of the water diversion surface of the pile on the water and underwater, respectively. We used the absolute coordinates of the laser point cloud with high accuracy, the point cloud of the water surface of the underwater pile is jointed, and the high precision absolute position of the water surface of the pile is obtained. Then, according to the absolute position of the water surface and the size of the pile, the point and slope of the part below the mud surface of the piles are calculated accurately. Absolute accuracy of pile positioning is 10 cm, which is verified by the location of wharf characteristic points. Finally, the measurement results of the old piles are compared with the design results of the new pile. The results show that there is a collision between new and old piles in the berth 2#, and 10 new piles and old piles in the berth 4# with a horizontal interval of less than 10 cm, which may occur in the construction process. |
