摘要
将独立分量回归引入大坝多点位移建模,并以五强溪大坝引张线若干测点的水平位移数据进行实验。结果表明,相对于逐步回归,独立分量回归有效解决了多测点回归建模中自变量多重相关性引起的病态问题,可建立稳定合理的回归模型。
In this paper,the independent component regression（ICR）is used in deformation analysis for dams;a multi-points model is built with ICR to analyze the deformation of Wuqiangxi dam.The modeling of Wuqiangxi dam deformation using the ICR method shows that ICR can solve the problem of multicollinearity of arguments and achieves a stable and reasonable deformation model.
