摘要
土石坝沉降主要是时效变形,一般采用回归模型进行分析。针对土石坝沉降的特点,引入了能反映工程动态变化的灰理论模型,介绍了灰理论的基本原理和灰建模的求解过程。结合陆浑水库实测沉降资料进行了分析,结果表明所建立的模型精度高,能反映沉降的最新变化趋势。
The settlement of earth-rock dam is mainly a deformation for a given period of time it is analysed with the regression model.The graytheory meodel,shown dynamic change of project,is adopted.The paper introduces fundamental principle and calculation process of gray model.The analysis with actual measurement settlement data of Luhun reservoir indecats that this model has a high precision, can show a new change trend of settlement.
