基于最小二乘法的地铁盾构隧道结构横断面测量方法研究
|
摘要
基于既能加快内、外业作业进度,又能满足现实测量工作条件的目的,文中以合肥某盾构隧道结构横断面实际测量作业为背景,提出了一种利用全站仪结合最小二乘空间拟合的方法对盾构隧道结构横断面测量数据进行处理。通过将该方法处理获得的数据与实际测量值进行比较,结果显示采用该方法对地铁盾构隧道结构横断面测量数据进行处理是可行且准确的。同时,在保证一定数目的测量点参与拟合计算的前提下,该方法可在一定程度上降低测量环境对工作的制约,使得工作效率大大提高。
The paper takes the shield tunnel cross-section measurement of actual operatic in Hefei urban rail transit construction as the background,it puts forward a method of measurement data processing which combines the total station and least square method. Compared with the design results,the calculated results by the least square method is feasible and accurate. At the same time,it reduces the influences of measurement environment on the survey work to some extent and it makes the work efficiency is greatly increased under the premise that ensure there is a sufficient number of measurement point in fitting calculation.
