螺杆桩静荷载曲线拟合及承载力预测

Static Load Curve Fitting and Bearing Capacity Prediction of the Screw Piles Based on MMF Model

采用MMF模型对实测的新型螺杆桩的荷载—沉降曲线进行拟合,并对螺杆桩的极限承载力进行预测,结果表明,MMF模型模拟和预测精度能够满足工程的要求,从而说明该模型的合理性和可行性,可为今后单桩极限承载力的确定提供一定的参考。

The MMF model was employed to fit the load - settlement curve of the newly - developed screw pile and predict the pile bearing capacity. The result showed that the accuracy of the simulation and prediction could satisfy the requirement of engineering. Therefore, the MMF model was proved to be reasonable and feasible and it also presented some reference for determining the ultimate bearing capacity of a single pile.
