灰色模型在建筑沉降预测中的改进与发展

灰色理论因其优良的灰色信息处理能力被广泛地应用于建筑沉降预测领域。但随着精度要求的提高，对灰色理论进行的改进从没间断过。从原始理论出发，结合近年来灰色预测模型发展的特点和存在的问题，总结了灰色模型在沉降预测中背景值、参数和控制量等方面的改进，分析认为下一步研究的重点将转向灰色模型方法改进，以及对灰色模型进行机理、权值组合方面的运用。

Improvement and Development of Gray Model in Settlement Prediction for Buildings

Gray theory, because of its excellent ability of gray information processing, is widely used in the field of building settlement prediction. However, as the increase of the accuracy requirement, the improvement of the gray theory is never interrupted. Based on the original theory and combined with the characteristics and issues with regard to development of the gray prediction model in recent years, the improvement in respect of background value, parameters and control quantity of the gray model in the settlement prediction was summarized. Through the analysis, it was thought that the emphasis of the following study will change to the improvement of the gray model method, and the application of mechanism and weight combination in relation to the model.
