Abstract

A methodology is developed to evaluate the vulnerability of bridge piers to scour and to help establish effective disaster measures, taking into account the locality and scour characteristics in Korea. Based on the bearing capacity of bridge foundation-ground integrating system changed by scour, this methodology is able to prioritize bridge foundations reflecting on the geotechnical factors as well as hydraulic ones. The bridge foundation vulnerability to scour is categorized into 7 groups considering the concise information of the bridge foundation-ground integrating system. A case study of implementing this method which includes the analysis of the scour depth and evaluation, and categorizing the scour vulnerability of bridge foundation is presented.
