非等间距GM(1,1)幂指数优化模型在变形监测中的应用

Application of Non-equidistant GM(1,1)Power Exponent Optimization Model in Deformation Monitoring

为提高非等间距灰色模型在建筑物沉降中建模的拟合效果和适用性。文章对灰色非等间距的幂指数进行了优化,并将模型应用于建筑物沉降进行预测分析,并与传统的回归分析模型进行对比分析,验证该模型在建筑物沉降观测中是否具有良好的拟合效果和适用性。通过实例分析,该模型在一定程度上提高了拟合效果,预测更加贴近真实值,可以满足变形监测的工作需要。

The fitting effect and applicability of the non-equidistant gray model in building settlement modeling were studied.The gray non-equidistant power exponents of the model were optimized and then the model was used in the building settlement prediction.The method was compared with the traditional regression analysis model.The results show that this model has a better imitative effect and applicability.
