Countermeasures to Protect Bridge Abutments from Scour ebook

NCHRP Report 587: Countermeasures to Protect Bridge Abutments from Scour will be of interest to transportation departments that are responsible for constructing and maintain- ing bridges that span waterways. This report provides selection criteria and guidelines for the design and construction of countermeasures to protect bridge abutments and approach embankments from scour damage. Typical approaches for protecting bridge abutments from scour are to mechanically sta- bilize the abutment slopes or realign the upstream flow.

Riprap is the most commonly employed countermeasure where bridge piers need to be protected against possible undermining by scour.

The aim of the experimental study was to determine the requirements of riprap and cable-tied block apron countermeasures to protect bridge abutments from scour damage, and to produce design guidelines for their use. The two types of bridge abutments used in the experimental study. The two types of bridge abutments used in the experimental study were a spill-through abutment situated on the floodplain of a compound channel, and a wing-wall abutment sited at the edge of the main channel

Bridge scour is the removal of sediment such as sand and gravel from around bridge abutments or piers. Scour, caused by swiftly moving water, can scoop out scour holes, compromising the integrity of a structure. In the United States, bridge scour is one of the three main causes of bridge failure (the others being collision and overloading). It has been estimated that 60% of all bridge failures result from scour and other hydraulic-related causes.
