摘要
Abstract
According to incomplete data of the single pile on the vertical static loading test, this research aims to predict the vertical utmost bearing capacity of the single pile by GM ( 1,1 ) model of the gray system theory, and to analyze the reasonableness and error of re- sults. Analysis about a practical engineering example indicates that the prediction of the vertical utmost bearing capacity of the single pile by the test data has comparative accuracy when the load reaches or exceeds the utmost bearing capacity of tree-quarters during the vertical static loading test, also the new information GM ( 1,1 ) model and the metabolic GM (1,1) model have more accurate prediction than the old information GM (1,1)model.关键词
