随工程进展的海堤沉降优性组合预测研究

Superior Combination Forecasting on Seawall Settlement with Project Progress

通过分析实测数据来预测沉降是实际工程中较多采用的方法.单一的预测方法各有其适用性同时也存在着不足,据此提出既能综合利用多种预测方法提供的信息又能提高预测精度的组合预测.在工程进展的过程中分期采用组合预测的方法,可以提高预测精度.并通过具体工程实例的分析,说明随工程进展的优性组合预测的有效性.

Settlement prediction is an important problem in soft-clay roadbed design and construction.The normal prediction methods,based on observation data,highlight its characteristics in applicability,as well as its disadvantages.A kind of combination forecasting with high precision is introduced in the essay based on overall information provided by different methods.The adoption of superior combination forecasting is helpful to improve settlement prediction precision in project progress,which is much better than the traditional one.The validity of superior combination forecasting is also illustrated by a project case.
