摘要
由于很多施工区域的地形较为复杂,对测量工作提出了新的要求,除改进常规测量方法外,同时需要更高效的仪器提供技术保障。本文以震后四川省九寨沟县鲜浒沟地质灾害工程1:500地形测绘项目为例,介绍了超站仪在地形测量中的应用原理,结合施工区,讨论了其实施方法、注意事项、对测量成果的重复性、复现性等问题进行了分析,提出了复杂地形测量的新方法。实践证明,超站仪在复杂地形测量工作中较常规测量仪器有较大的优势。
In recent years, due to the rapid development of infrastructure and the conduct of the ＂5.12＂ post-disaster reconstruction in China, topographic measurements increased significantly. However, as many of the construction area of the terrain is more complicated, for measurements made new demands, in addition to improving the conventional measurement methods, more efficient e- quipment are also needed to provide technical support. In this paper, taking Xianxugou 1 ： 500 post-earthquake Geological Disaster Engineering Projects in Jiuzhaigou County of Sichuan Province for example, it introduced the principle of super total station in topo- graphic measurement. Combined with the construction area, it discussed hte implementation methods, notes, measuring result＇ s repeatability and reproducibility and so on were analyzed. Finally, a method of measuring in complex terrain was taken. Super total station had more advantage than common measurement instruments in complex topographical surveys. This method would have a significant impact on other surveys.
