高填方路基的沉降变化规律及其预测方法研究

Study on Settlement Rules and Prediction Method of High Backfill Subgrade

通过对高填方路基沉降变化的分析与研究,总结出其沉降变化的发展规律,建立了泊松曲线和龚帕斯曲线组合而成的模糊自适应变权重组合预测模型。通过运用该组合预测模型预测实体工程的沉降变化,证实了该方法比单一预测模型具有更高的预测精度与更佳的适用性。

Through analysis and study of settlement rules of high backfillsubgrade, this paper summarizes the development rules for settlement, so to set up fuzzy serf- adaptable variable weight combined prediction model integrated with Poisson curve and Gonepass curve. With application of this integration, we can predict the settlement of sample project. The result shows this method has higher prediction precision and better adaptability than mono- prediction model.
