根据拉格朗日中值定理建立了变权背景值构造形式,背景值权值采用具有全局寻优能力的模式搜索法求解,工程实例应用结果显示基于模式搜索法改进的单桩极限承载力灰色预测模型提高了预测精度,具有更好的工程应用价值.%According to the Lagrange's mean value theorem, the paper established variable weight background value structure form. The background value right value uses pattern search method of global optimization ability to solve, engineering example application results show that the improved single pile limit bearing capacity grey forecasting model based on pattern search method improves the accuracy of the predictions, and has better applied value in engineering.
