摘要
结合灰色预测的检验方法,将后验差比值作为目标函数,采用遗传算法对单桩极限承载力进行了预测。应用实例表明,与传统灰色预测法相比,该方法能有效减小预测结果的后验差比值,并能得出更合理的桩基极限承载力。
By combining with the testing methods of the grey prediction, the paper takes the anaboly difference as the objective function, adopts the genetic algorithm to predict the ultimate bearing capacity of the single pile. It is shown by examples that the method, by comparing with the traditional grey prediction method, can effectively reduce the anaboly difference in the prediction results and can obtain a more reasonable the ultimate bearing capacity of the pile.
