摘　　要：为深入研究水库载荷的变化对周边地倾斜观测的影响,根据不规则载荷模型方法,分析佛子岭水库每增加106 m^3水体载荷造成的影响特性。结果表明:在理想状况下,载荷变化造成的影响,呈有界性、单调性和非均匀性。对比研究仪器观测数据与模型预测数据可知,二者之间在NS分量差异较大,EW分量差异较小,说明模型只可用于理想条件下的初步预测。In order to study the influence of reservoir load change on surrounding ground tilt observation,we analyzed the influence characteristics of each additional 106 m^3 water load in the Foziling reservoir based on the method of irregular load model.The results showed that the influence of load change was bounded,monotonous and non-uniform under ideal conditions.After comparison between instrument observation data and model prediction data,we found the differences between them were large in NS component and small in EW component,which indicates that the model can only be used for preliminary prediction under ideal conditions.
