摘要
利用矩阵平行加的性质推证：工程建筑物变形分析的变形参数γ的计算可归纳为对变形模型｛ｄ，Ａγ，Ｑｄ｝的平差计算；利用原模型与变形模型分别平差计算的残差二次型Ｐ及ＶＰｄＶｄ，可方便地进行变形模型的统计检验。基于以上推证，编制了相应的计算程序，并且结合一个水工建筑物变形监测网实例进行了计算分析，得出了与实际情况基本相符的结论。
By using the properties of parallel sum of matrices, the author derives that the calculation of deformation parameterγcan be summarized from the adjustment of deformation model {d,Aγ, Qd}.In this paper, the author also presents that the deformation analysis can be conducted with the residual quadratic form of deformation model and original model. Based on the previous conduction,a software is developed, which can be used in the adjustments of the measurements, the tests of the deformation models and the selections of the optimal deformation models. Finally, a practical calculation and analysis of an engineering monitoring network is given.
