摘要
针对工厂中大型烟囱的水平截面为圆形的特点,本文提出了一种基于间接平差法的垂直度监测方法。该方法是利用高精度的全站仪获取烟囱不同高度水平截面外边缘坐标,根据间接平差原理求解不同高度水平截面的圆心坐标,然后通过计算不同高度截面圆心坐标差,评判烟囱的垂直度。
In this paper,a vertical monitoring method based on indirect adjustment method is proposed for the circular horizontal section of large chimneys in factories.The method is to obtain the outer edge coordinates of the horizontal section of the chimney with different heights by using the high-precision total station,solve the coordinates of the circular center of the horizontal section with different heights according to the principle of indirect adjustment,and then judge the vertical degree of the chimney by calculating the difference of the coordinates of the circular center of the section with different heights.
