摘要
针对打桩定位的测量方法,探讨了一种用于海上打圆桩过程监测的新型测量方法,使用全站仪无棱镜模式对圆桩横切面进行数据采集,应用最小二乘原理迭代拟合横切面,得到拟合圆心的坐标及圆半径,进而解算桩顶位置和高程、桩倾斜度及多桩控制,实现打桩过程动态监测。经过某项目打桩案例实践,验证了该测量方法的可行性和正确性。
In view of the measurement method of pile driving position, the new measuring method is discussed for monitoring the driving process of round pile at sea.The cross-section data are collected by the prism-free total station, to fit iteratively the coordinates and radius of the cross section with the least square principle.This method is used to solve the pile top position and elevation, inclination, and multi-piles control by the software, to realize the dynamic monitoring of pile driving process.In a pile driving case,it is proved that this method is feasible and correct.
