摘要
本文阐述了多元逐步回归方法的优点,介绍了该方法的建模过程及其计算程序框图,在铁路隧道建设工期定额编制中,成功地应用于围岩类别与施工进度之间关系的分析。
In this paper, the advantage of the multiple element regression in step-by-step is described. The establishment of mathematical model and the flow chart of this program is recommended. Its application to the relation between the classification of rock around tunnels and construction progress in the preparation of constrution duration quota for railway tunnels is described.
