管道航测作业应注意的问题及解决措施

Matters Needing Attention in Pipeline Aerial Survey and Countermeasures

以航测为主要手段获取基础空间数据,通过GIS平台辅助管道工程设计,是目前航测在管道工程建设中的主要应用模式。航测技术为深化管道工程设计工作、缩短设计周期和提高设计质量奠定了基础。为了更好地发挥航测技术的作用,结合西气东输二线管道工程,就管道航测作业过程中应该注意的问题进行了详细分析,并提出了解决措施。

At present, it is the main application mode of aerial survey in pipeline engineering that basic spatial data are acquired by aerial survey and pipeline aided design is made by means of GIS platform. Aerial survey technique founds the basis of pipeline engineering design in enhancing design depth, shortening design period and boosting design quality. In order to further develop the aerial survey actions, this paper analyzes in detail the matters for attention in pipeline aerial survey operation based on the practice of Second West to East Gas Pipeline Project, and puts forward some countermeasures.
