| 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。

| Abstract: | 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. |
