预应力管桩极限承载力的灰色预测

Prediction of the ultimate bearing capcity of prestressed pipe pile using grey system theory

运用灰色系统理论中的GM(1,1)模型,对桩的不完全静载荷试验p-s曲线进行预测,可以很好地解决工程实践中如何根据未达到破坏试验资料确定预应力水泥混凝土管桩的极限承载力的问题,且具有可靠的精度。

The author predict p-s curves of partially static load test with grey system theory.By use of GM（1, 1） prediction model in grey system, the determination of ultimate bearing capacity of pretensioned spun concrete pile can be carried out with the data from unbroken testing piles.
