Study on Slope Failure & Remediation of Bridge Abutment Highway No.2133, Si Bun Rueang - Phu Wiang Route sta. 31+087

Bridge abutment slope failure, Scour, Factor of SafetyAbstract
The bridge is a building used for crossing the river or crossing an obstacle, for the benefit of traffic and also serves to drain the water as well. When the bridge is damaged causing insecurity route users. The damage of the bridge takes many forms, the main cause of the damaged caused by flooding and scouring around the bridge substructure. However, the problem became more severe due to climate change making each year more prone to flooding. Combined with the longer life of the bridge will result in the risk of the bridge abutment slope failure. This paper presents the study of stability analysis of the bridge abutment slope in soil moisture content conditions and different scour depths, to find the factor of safety. Which results from stability analysis shows the cause of the failure of the bridge abutment slope. The failure will occur in the soil high moisture content conditions and the scour depths more than approximately 1.20 meters.
