灰色理论和Usher曲线预测CFG桩承载力的研究

The study on bearing capacity of CFG pile by Grey theory and Usher curve prediction mode

针对现行规范公式计算煤矸石型CFG桩极限承载力存在偏低的问题,建立了灰色GM(1,1)模型及Usher曲线,预测了煤矸石型CFG模型桩极限承载力,得出了一些有价值的结论,为类似煤矸石型CFG桩极限承载力的预测提供借鉴。

In view of the problem that calculating the ultimate bearing capacity of coal gangue pile CFG pile is low by the current code formula,basing on Grey GM（ 1,1） model and Usher curve to predict the ultimate bearing capacity of coal gangue CFG model,it can provide the reference for predicting the ultimate bearing capacity of coal gangue CFG model pile in similar projects.
