高速公路项目交叉工程成本预测方法研究

Research on the prediction method of crossing engineering cost in freeway projects

高速公路交叉工程成本预测是高速公路造价评估中的重要内容,分析研究了交叉工程建安费的构成,提出了决定成本的主要指标及量化方法。根据不同类型的交叉工程建设的历史统计数据,建立神经网络预测模型并以河南省境内所有交叉工程历史数据为预测样本,经过误差控制性分析,样本预测结果表明该方法可行。

Crossing engineering cost analysis of freeways is an important content of freeway cost evaluation.The paper has done some research on the composition of construction cost of the crossing engineering,and puts forward the main index of cost control also with the quantization methods.According to different kinds of constructional statistical data of crossing engineering,the paper establishes the neural network prediction model.Then,it is applied into the crossing engineering prediction by the historical data o...
