基于实测数据的高填方工后预测模型研究

Based on the Measured Data Prediction of the Post-Construction of the High Embankment

以某高填方工程沉降地表点实测结果为基础,探讨了高填方工后沉降预测回归参数模型。在对数曲线模型、指数曲线模型、双曲线模型以及抛物线模型等回归参数模型分析研究发现,只有指数曲线和双曲线模型能较好反映高填方工后沉降规律。随着回归分析所用的监测数据时间越长,预测精度增大,预测效果越好。

Based on the measured result of high embankment settlement surface,this paper discusses settlement prediction work after high fill regression model parameters.Through the comparative analysis of the logarithmic curve model,exponential curve model,hyperbolic and parabolic model and other model parameter models,it has been found out that only exponential and hyperbolic model can better reflect the post-construction settlement of high fill rule.And the longer data-monitoring time used in the regression analysis,the more accurate the prediction is,the more effective the forecast is.
