Flood-induced Bridge Failures in Papua New Guinea
Papua New Guinea has been experiencing frequent bridge failures and collapses due to flooding rivers in the recent past. According to the records from Papua New Guinea Department of Works, it is estimated that over Two Hundred and Eighty (285) bridges, fords (causeways) and major culverts were damaged by flood action alone in the last five years between 2013-2017. That is approximately at an average rate of 57 bridges in a year. This result is very disturbing and as such this study was undertaken to assess and analyze the flood-induced bridge failure causes and offer applicable solutions. This study will report on the field investigation works and results derived from the twenty-one flood affected bridges in six different major road networks in three provinces of Papua New Guinea. Hence, it was observed in this study that substructure damages due to flooding account for seventy percent (70%) of the bridge damages while superstructure damages account for the thirty percent (30%). The common causes of flood-induced bridge failures were identified as local scour around bridge piers and abutments, contraction scours, sedimentation, debris, and log impact.
