摘要
以武汉阅马场交通综合整治工程中省重点保护文物单位红楼为研究实例,运用指数平滑法,在Excel软件中实现最优平滑系数的选择,进而预测临近重点文物建筑物基坑支护结构桩顶的水平位移。分析结果表明,指数平滑法对于曲线变动趋势的时间序列预测的十分接近。
Based on the project of the provincial cultural relics Honglou in the cut-cover tunnel in Shouyi square of Wuhan,this paper adopts the exponential smoothing method to choose the optimal smooth coefficient by means of Excel and predict the horizontal displacement of the pile head in the deep foundation retaining structure.It concludes that exponential smoothing method is fit for predicting the time series trend curve.
