建筑物变形预测模型的对比分析

Comparison and analysis of building deformation prediction

运用灰色GM(1,1)和自适应Kalman滤波两种模型,分别分析了某砖混结构建筑物的沉降变形趋势,并借助MATLAB2014平台编写了两种模型的拟合程序,基于此砖混结构建筑物的实测沉降数据,对两种模型进行了变形预测,通过这两种模型预测值与实测值的对比及模型误差的检验表明,自适应Kalman滤波模型在变形预测方面具有一定的优势。

Using the grey GM( 1,1) and the adaptive Kalman filter model analysis a brick concrete structure building settlement deformation trend respectively. Through with MATLAB2014 is developed on the platform of the two kind of model fitting procedure. The measured settlement data of a brick concrete structure building was trained on two kinds of model and the deformation prediction based on. Through the comparison of the measured and predicted values of the two models and the test of the model error,the adaptive Kalman filtering model has some advantages in deformation prediction.
