Abstract
The relative deformation value measured at the stage of closing and pushing of continuous rigid frame bridge appears difference from the model theoretical calculated values in most cases, because most models ignore the pile-soil effect and simplified consider the bottom of the pier as consolidation. At the same time, most literatures use single pile-soil effect model to analyze the stress influence on bridge structures, however, there are few researches on the difference and simulation accuracy of the different pile-soil effect model. Therefore, this paper discusses the advantages and disadvantages of six different pile-soil effect calculation models, and determining high pier optimal calculation model of rigid frame bridge by comparing and analyzing the relative displacement of the top closure. Last, this article gets the conclusion that the three-spring model is the optimal calculation model of high pier under pile-soil effect.
