摘要： 通过对复合地基沉降发展机理和规律的分析,结合Verhulst灰色预测模型的特点,建立了复合地基沉降的Verhulst灰色预测模型,反映了复合地基沉降 时间曲线的单调递增性、有界性和呈"S"形的特点·模型精度检验表明,利用较少的沉降观测数据,通过数学推理过程建立的沉降Verhulst预测模型具有可靠的预测精度,反映了复合地基沉降发展的长期过程·

Abstract: Based on an analysis of the developing mechanism of composite foundation settlement in combination with the characteristics of Verhulst gray model, a Verhulst gray model for the composite foundation settlement was specially developed to reflect the characteristics of settlement-time curve, such as its monotone increasing, boundedness and S-shape. The precision check proved that by such a Verhulst gray model less observing data are required to set up a prediction model with reliable precision through a mathematical reasoning process, which will reveal the long settlement process of composite foundation.
