Gray Prediction to the Settlement of Pile Foundation
-
摘要: 利用实测的桩基静载试验数据,用灰色系统理论建立桩基沉降量的灰色GM (1,1)预测模型,可以模拟桩基静载试验P-s曲线的未知部分。研究结果表明,建立的GM (1,1)模型可有效预测桩基沉降量,对进一步分析桩基的承载性能有理论与实际意义。Abstract: A GM(1,1) model is established by Gray Theory using observation data of loading tests for pile. The model can be used to predict the unknown part of p-s curve of pile loading tests. The result of study shows that GM(1,1) model can effectively predict the settlement of pile foundation, and be of the theoretical and actual meaning for further analysing the bearing capability of pile foundation.
