摘要
介绍了偏最小二乘法的建模基本思路和交叉有效性判别方法,编制了偏最小二乘回归程序,与弹性力学有限元联系,建立了基于偏最小二乘回归的大坝位移混合模型。算例分析表明,建立的模型有较好的拟合和预报功能。
The basic model method and the cross validation of partial least square (PLS)are discussed, and the programme of PLS regression is compiled. Combined with finite element method, the hybrid model for computing the displacements of dam is set up and a compute example is given. The result computed with this model is very close to monitoring data in situ, and very effective for forcast.
