| 摘 要： | 一般的观测方法难以实现对海上测风塔整体垂度的测量。文章根据实际观测经验,给出了一套较为完善的观测方法,实现了仰视全方位观测,利用误差理论控制误差传播,减少了误差积累,削弱了测距误差的影响,大大提高了观测精度和作业速度。同时对测量误差进行了分析论述。

| Abstract: | It is difficult to implement the perpendicularity survey of the offshore wind tower with the conventional measurement.According to the practical working experience, a relatively perfect observation method was proposed in this paper.The omni-directional observation has successfully achieved using this method.The error accumulation and propagation were reduced by means of error theory,the influence of ranging error was weakened,the accuracy and speed of surveying were improved greatly.Meanwhile, the error analysis of surveying was described. |
