单桩极限承载力的灰色预测

Grey Prediction of Ultimate Bearing Capacity of Single Pile

运用灰色理论 ,建立了荷载与沉降的 GM( 1 ,1 )模型 .结合某根桩的静载试验结果 ,对该桩的荷载与沉降分别进行了预测 ,并在只有部分实测结果的情况下 ,对单桩的极限承载力进行了预测 .预测出完整的荷载沉降曲线 。

In this paper,the grey prediction model GM(1,1) is established to predict load and settlement. Based on part of the data of static load test,the ultimate bearing capacity and the whole load settlement curve is also predicted. The experimental results is consistent with the predictions.
