The Statistical Test of Deformation Model

This paper first introduces the principles of testing the generalized parameters and then it proves that the two solutions of deformation parameters,Y,——one of them obtained by the adjustment of deformation model,and the other,by the adjustment of the restrained model——are consistent.The author has also revealed that the residual quadratic form of the deformation model is equal to the subtraction of the residual quadratic form of the original model from the residual quadratic form of the restrained model,that is,V_d^TP_dV_d=???.Finally,as an example,adjustment has been made of the original model and the deformation model and statistical tests on the deformation model have been performed on the basis of the observations done on the monitoring network of a certain dam over two periods.
