利用灰色理论对地基沉降进行不等时距预测

Application of Grey Theory in Unequal Time-span Forecast of Ground Settlement

摘要:

应用灰色理论 ,建立了不等时距的地基沉降预测GM ( 1 ,1 )模型 ,并可对结果进行修正。利用该模型对某 1 2层住宅地基沉降进行预测 ,预测结果精度高于常采用的双曲线模型推算结果。

Abstract:

GM(1,1) model of unequal time span forecast of ground settlement is established based upon Grey theory. The result can be amended. The model was applied to forecast the ground base settlement of a 12 storey building. The accuracy of the results got by this forecasting model is higher than that of common hyperbolic model.
