大直径超长混凝土灌注桩极限承载力预测
Ultimate Bearing Capacity Prediction of Super-long Large Diameter Bored Pile
摘要
Abstract
3 super-long and large diameter bored piles of 32 stores height building in Zhengzhou were selected to carry on the satic experiment research. A CM (1,1) information renewal model is presented by using the load-settlement data of piles to predict the pile bearing capacity. The results show that the CM (1,1) information renewal model can timely add new information to pile top displacement and remove the old information,which greatly improve the prediction accuracy.关键词
