摘要
通过分析公路施工定额现场测定原始数据的差异性及引起差异性的各种影响因素,基于改进的非线性主成分算法,对各影响因素进行分析.在辅助软件SPSS的支持下,结合实例,得出影响施工定额测定因素的归类解释,可为实际定额测定过程中某道工序的测定规程及主要影响因素提供参考.
The differences between the original data of the highway construction quota caused by various influencing factors are analyzed,using the improved algorithm of the nonlinear principal component to analyze every influencing factor,and then being calculated with examples of influencing factors＇ interpretation to classify,which provides consultation in the procedures of the actual measurement process and certainty of the main factors.
