湿陷性黄土地区城市排水管道费用模型研究

文章通过分析湿陷性黄土地区大量己经建成的城市排水管道建设费用资料,采用统计分析方法,运用最小二乘法对不同条件下实际费用进行回归分析,得到城市排水管道工程费用与主要参数(管径D、管道埋深H)之间的费用模型函数,其结论可对陕西、甘肃及山西等地区项目方案比选、经济分析以及排水收费定价提供理论依据和实际价值。

Research on City Sewer Project Construction Cost Model in Collapsibility of the Loess Region

By analyzing a large number of city sewer project construction cost data that has been built in collapsibility of the loess region,and using statistical analysis methods,regression analyzing the actual cost data under different conditions by using least squares,this article gets the cost model function between the city sewer project and the main parameters(diameter D pipeline depth H).The conclusion can provides a theoretical basis and practical value to saving design,technical and economic analysis and drainage fee pricing.
