摘　　要：本文对静载试验中未达到极限状态时预测单桩极限承载力的几种方法进行了比较。根据现场静载试验数据应用双曲线模型和灰色系统理论模型对极限承载力进行预测,最后进行了对比分析。This paper introduce the comparison of prediction methods of single pile ultimate bearing capaciW （PUBC） when test load was not reach to the ultimate value. And then, based on the site test record, the prediction PUBC value with hyperbola method and gray prediction model will be worked out separately.As a conclusion,the empirical result and prediction result will be compared and analyzed.

关 键 词：单桩极限承载力预测 双曲线模型 灰色系统理论预测模型
