Stability Analysis of Scour around Exposed Bridge Pier

Abstract:

Instability exposed foundation due to scour around bridge pier caused displacement should be noted that erosion and destruction often occurs subsidence of river-bed soil in bearing layer changed place under water pressure bound to tilt the piers of the bridge, which can then produce another phase of secondary displacement, that is, if in the longer term forces such as earthquakes or floods overall resulting short and long term in unstable state. This study applied finite element model Plaxis-2D to analyze exposed foundation on bridge pier scour in 200-year return flood peak flow, involving consolidated with static load, water pressure, structures suffered the wind, driftwood impact, and debris thrust is to assess abutment security in flood erosion according to the alert and action warning.
