| Abstract: | 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. |
