边坡形变Verhulst建模及后验差检验

Slope Deformation Verhulst Modeling and Posterior Difference Test

基于GNSS监测数据,采用Verhulst模型对水库边坡区域地表沉降与时间问题进行建模研究,并以后验差检验法对建模结果进行验证。结果表明,该模型计算简单,模型参数较少,预测精度较高,能够有效的表征边坡监测体的沉降变化规律。

Based on the GNSS monitoring data,the Verhulst model is used to modeling the surface subsidence and the time problem in the slope area of the reservoir.The model test results are verified by the post-test difference method.The results show that the model is simple,the model parameters are less,the prediction accuracy is higher,which can effectively characterize the variation of slope monitoring body settlement.
