采用Richards模型对实测的新型螺杆桩的荷载—沉降曲线进行拟合,并对极限承载力进行预测,结果表明,Richards模型拟合效果比指数模型、双曲线模型要好,模拟和预测精度能够满足工程的要求,从而说明了Richards模型的合理性和可行性,可为今后螺杆桩单桩极限承载力的确定提供一定的参考。 The Richards model was used to fit the load-settlement curve of the new type of screw pile measured, and the ultimate bearing capacity was predicted. The results show that the fitting effect of Richards model is better than the exponential model and hyperbola model, and the simulation and prediction accuracy can meet the engineering The results show that the Richards model is reasonable and feasible, which can provide reference for the determination of the ultimate bearing capacity of screw pile in the future.
