灌溉管道造价函数研究

确定某个地区的灌溉管道的造价函数,需要收集当地单位长度灌溉管道的工程造价资料,但目前造价资料收集较为困难,且有些管道灌溉工程建设年代较早,其造价已不能反映目前的价格水平。针对以上问题,引入市场材料造价信息、工程预算定额等内容计算各种管径管道的工程单价,再经过统计分析得出灌溉管道造价函数。

Researches on cost function of irrigation pipes

To define the cost function of irrigation pipes of certain region,engineering cost data of irrigation pipes per unit length in the region are needed. However,the cost data are difficult to collect,and the cost of some irrigation projects cannot reflect the current price level owing to their old construction time.With regard to the above-mentioned,cost information of market materials and budget norm of engineering,etc.are introduced to calculate the engineering unit price of pipes with various diameters,and then through statistical analysis,the cost function of irrigation pipes is yielded.
