困难山区铁路主要技术标准与工程投资关系研究

铁路主要技术标准与工程投资有着十分密切的关系,通过深入探讨铁路主要技术标准,从统计学的角度研究铁路主要技术标准与工程投资的关系,建立工程投资关于铁路主要技术标准的多元非线性回归模型。并结合实际算例说明回归模型的良好的拟合度,研究各项主要技术标准之间的相关性,分析各项主要技术标准对工程投资的影响趋势与影响程度,从而在实际的应用中能够有的放矢地关注关键的技术标准以及科学合理地决策出各项主要技术标准,以达到优化线路设计、节约工程投资的目的。

Research on Relationship between Main Technical Standards and Project Investment for Difficult Mountain Railways

The main railway technical standards correlate closely with project investment. Based on intensive discussion on main technical standards and the researches on the relationship between main technical standards and project investment for difficult mountain railways in perspective of statistics,the nonlinear regression model of project investment related to the main technical standards is established.With reference to practical examples,the good fit of regression model is illustrated,and the correlation between the main technical standards is studied,and the influence trend and influence degree of the main technical standards on the project investment are analyzed to allow attention to be focused on key technical standards in practical application and to define scientific and rational technical standards for the purpose of optimizing location design and saving project investment.
