Abstract
Many researches have been devoted to developing a model fur bridge scour analysis which can consider both of the erosive potential of flowing water and the relative ability of the soil to resist erosion. The scour rate apparatus that can quantify the erosion rate of the soil has been developed by virtue of the extensive efforts. The scour rate tests were performed on 3 types of the remolding clay samples using the scour rate apparatus. The erosion characteristics of the fine-grained soil samples according to the variation of the remolding loads are examined and the correlation between the soil properties and erosion rates is also analyzed. The results of the tests and analyses show that the soil properties, especially the dry unit weight and the shear strength of the soil have great influence on the erosion characteristics.
