变形模型运动参数的筛选和运算
FILTERING AND CALCULATION OF DYNAMICPARAMETERS IN DEFORMATION MODEL
【摘要】 进行多期复测水准网平差和变形分析,模型中运动参数的选取,不仅涉及计算工作量而且会影响分析结果的正确性。本文运用统计检验方法对运动参数筛选,结合参数估计给出了扫描运算方案,通过对多期复测模拟水准网进行的试算,说明所给方案是有效的。本文是文献〔1〕所述理论的应用,也是多期复测水准网平差和分析的实施方案。
【Abstract】 In the adjustment of leveling network repeated over several periods and in deforma-tion analysis. it is of considerable importance to make right choice of dynamic parame-ters in deformation model. not only does it have direct bearing on the volume of com-paputation work. but it also affects the righteousness of the results of analysis. In thispaper. statistical test is applied to the filtering of dynamic parameters: combined withparameter estimation. a scanning program is worked out. The program is validated bytaking a simulated leveling network repeated over several periods as an example.The statement of this paper is an application of the theory formulated in [1], it is also a practical program for adjusting and analysing leveling network repeated overseveral periods.
