Analysis for Prediction of Settlement of Soft Soil Foundation Based on Grey System
Based on on-site settlement monitoring data of Jinhai phase Ⅲ foundation reinforcement project in the Binhai New Area of Lianyungang City,Grey Model GM(1,1)is used to predict,calculate,and compare the settlement amount of reinforced foundation in Jinhai phase Ⅲ foundation reinforcement at Lianyungang City.The research shows that GM(1,1)meets the accuracy requirements,has high reliability and applies to real projects compared to Poisson method,Three-point method and Asaoka method.Furthermore,the analysis of predicted data shows that GM(1,1)gradually produces more errors with the increment of prediction time.In the case,Grey modeling method does not apply to medium or long-term settlement prediction.However,short-term settlement prediction results can reach the required accuracy.
