摘　　要：针对工程中经常遇到未达破坏的单桩极限承载力的确定问题,提出利用双曲线模型、指数曲线模型和灰色模型预测单桩的竖向极限承载力。工程实例表明,双曲线模型应用有一定局限,指数曲线模型和灰色预测模型的预测精度高且适应性较好,推荐普遍采用。To determine the ultimate bearing capacity of an individual pile which is an important engineering problem frequently encountered.The prediction methods of the hyperbola,exponential curve,and grey forecasting model are purposed.Engineering examples show that the application of hyperbola method is limited and the precision is lower than others.The precision of the gray and exponential curve prediction method is accurate,adaptability and can be widely applied.
