| 摘 要： | 为分析填筑期土石坝的沉降监测资料，探讨沉降发展与填筑施工间的因果关系，根据灰色模型建模数据量要求较少、拟和效果好的优点，以及该类模型中影响因子形式可以灰色抽象的特点，在借鉴相关沉降计算分析方法的基础上，将填筑影响下的土石坝坝体沉降影响因素分为与时效无关和与时效相关两类，采用填筑高度和等效高度作用因子为相关序列，利用灰色GM(1，h)模型建立沉降-填筑间的关系方程，以揭示填筑期间沉降规律并加以预测．算例表明，沉降-填筑安全监测模型有效地反映了土石坝施工期沉降规律以及沉降与填筑施工间的内在联系．

| Abstract: | In order to analyse embankment dam settlement survey data during construction and describe the relationship between the settlement and fill, the grey model has been considered because of its excellence. Two kinds effective factors of embankment settlement during construction stage were obtained based on the correlated settlement calculation methods. There are fill height and equivalent fill height effecive factor.GM(1,h) model is used to establish the equation between settlement and construction process to describe and forecast the settlement's disciplinarian. The example shows that the settlement-fill monitoring model fits the settlement regulation and reflects the relationship between them very well. |
