摘要:
影响地铁工程造价的因素很多，从而导致突破工程总造价的现象频繁发生。针对该现象，本文对影响地铁工程造价的主要因素进行了探讨。在探讨的过程中发现，很多影响因素都受到材料价格的影响，而地铁工程项目施工工期一般较长，在这期间人材机价格波动必定很大。故本文从定性、定量的角度出发，利用ARIMA模型对主要材料价格进行预测，达到主动、动态控制的目的。There are many factors that affect the subway project cost, which lead to a breakthrough in the total cost of the project. According to this phenomenon, this paper discusses the main factors which influence the construction cost. While I am studying, I find that many influencing factors are subject to the influence of material price, and subway project construction period is generally longer. In this period, artificial material mechanical price fluctuations will be great. From the angle of qualitative and quantitative, the paper takes the ARIMA model to predict the price of the main material, and then, the purpose of the initiative and the dynamic control is reached.
