| Abstract: | It is regarded as a grey system for the bearing capacity of the pipe pile based on the static load test.The GM(1,1) model in grey system theory is used to predict the Q~s curve of the partially static load test of the PHC pipe pile.The new method,which predict the change of late period of the Q~s curve according to the data from unbroken testing,is carried out.From the examples,it is shown that there is high accuracy. |
