回归分析是一种概率统计方法,也是定量分析大坝观测资料的有力工具,由于计算工作量较大,一般均需采用电子计算机进行计算。本文着重介绍了包括对大坝观测资料进行预处理的ALGOL-60电算程序及其使用,并给出了算例和程序框图,可供具体计算时参考。本文的有关内容不仅适用于大坝,而且适用于水闸、隧洞、管道等各种水工建筑物内部和外部观测资料的多元和逐步回归分析。 Regression analysis is a kind of probability and statistics method, which is also a powerful tool for quantitative analysis of dam observation data. Because of the computational workload, it is usually calculated by computer. This article focuses on the ALGOL-60 computer program which includes the pre-processing of the dam observation data and its use. The examples and the block diagrams are given for specific calculations. The relevant contents of this paper not only apply to dam, but also to multivariate and stepwise regression analysis of internal and external observation data of sluice, tunnel, pipeline and other hydraulic structures.
