摘要
鉴于引起建筑物变形的地质、水文、气候、附近开挖等原因的不确定性和各种因素影响度的不确定性,本文提出将基于AIC准则的回归理论应用到变形分析中,实现了多项式回归系数和幂次方的自适应处理,并实现了建筑物变形分析中变形因子和回归函数的自动确定。在MATLAB下编写了算法,并提出了优化方案。实践证明,这一理论很适合于变形分析。
Because of many unknown or uncertain factors which could trigger building deformation, such as geology, hydro, climate or nearby excavation, therefore, the regression theory based on AIC norm was used in deformation analysis. Both the power and the parameters of polynomial were fitted automatically. The automatic choice and conformation of deformation factor and regression function were realized on building deformation monitoring. Then, this arithmetic was prograrmned in MATLAB. The optimum schemes were presented. This theory has been proved useful and helpful in deformation analysis.
