高铁无柱雨棚工程造价估算与敏感性分析

影响高铁客运站无柱雨棚结构工程造价的因素很多,在收集已建高铁客运站无柱雨棚结构工程造价数据的基础上,针对侧式客站无柱雨棚结构工程造价选取了相应的几个主要影响变量。根据多元回归分析理论,分别建立了多元逐步线性回归模型和二次响应曲面模型,通过拟合模型的对比分析与实例验证,提出二次响应曲面模型在高铁侧式站无柱雨棚结构工程造价估算上的应用前景。并在此基础上,应用二次响应曲面模型研究得出各主要敏感因素对无柱雨棚结构工程造价的敏感程度。从投资角度为高铁侧式站无柱雨棚结构体系设计和建设提供了优化方向。

Project Cost Estimating and Sensitivity Analysis of Canopy without Columns in High- speed Railway

There are many influence factors of engineering cost of canopy structure without column in high - speed railway sations. Based on collecting the project cost data of canopy structure without column in high - speed railway sations, several main influencing variables are selected for lateral stations. According to the theory of multiple regression analysis, multiple stepwise linear regression model a quadratic response surface model are established. Through the contrast analysis and example verification of the fitting model, the prospect of application of quadratic response surface model is put forward And on this basis, the major sensitive factors on the sensitive degree of the project cost of canopy without column is researched by the application of quadratic response surface model. The system design and construction optimization direction is provided for lateral standing canopy without column structure in high - speed raiway from the Angle of investment.
