Abstract
In this study, using Winklerian model, five different companies made attempts to predict the performance of braced wall excavation with floating type earth retaining wall in a model site For one location, three different type of predictions were carried out without any observed data, Type A, with observed data until the second stage excavation, Type B, and with all observed date, Type C. Type D prediction was also done for the other location using the input parameters derived in the Type C prediction. By comparing the results of these predictions with the observation, discussed were effects of input soil parameters on the prediction and validity of various conditions assumed in the current design methods using Winklerian model.
