Study on Application of Asaoka Method on Settlement Prediction of Pile Foundation for High Speed Railway Bridges

Asaoka method is one of the main methods in settlement prediction of pile foundation. Asaoka method estimates final settlement data according to an unknown data calculated from the actual settlement observation. It is simple and has high accuracy and reliability features in the prediction. For this reason, Asaoka method has been widely used because of the good prospects forecast in the pile settlement. However, there are also two shortcomings of Asaoka method: (1) the choices of starting time influence the correlation coefficient and completion rates; and (2) the time interval also has a direct impact on the final settlement prediction result. Based on the large field testing settlement data of pile foundation of high speed railway bridge, the authors can make the predictions get closer to the actual results through the suitable choice of starting time and time interval.
