层次分析法在山区高速公路边坡防护工程面积测量方案优选中的应用

Application of Analytic Hierarchy Process in Optimization of Area Measurement Scheme for Slope Protection Engineering of Expressway in Mountain Area

结合山区高速公路边坡面积测量工程实践,对皮尺、全站仪、GPS-RTK三种测量方式进行比选,设定准确性、可操作性、可验证性、经济性和安全性等五项指标,采用层次分析法计算分析,结果表明,以现有的应用水平,皮尺法为最优方案,推荐在全线边坡防护工程面积测量中采用。

In combination with engineering practice of area measurement for slope of expressway in mountain area,comparison and selection are made for three kinds of measurement modes like tape measurement,total station survey and GPS- RTK measurement. Five indexes like accuracy,operability,verifiability,economical efficiency and safety are set,and analytic hierarchy process is adopted to calculate the analysis. The result shows that tape measurement is the most optimal scheme in current application level,which is recommended to be adopted in area measurement for slope protection engineering of the whole line.
