Prevention methods for lateral movement of abutment include increasing the bearing capacity of foundation, improving the soft ground and reducing the external loads. These methods are usually adopted prior to the bridge construction. However, it is not easy for them to be applied to the bridge during common use. Because they are not only difficult to be constructed, but also potential causes of stability of the bridge. Instead, counterweight fill, grouting and permanent anchorage can be considered as alternatives when the lateral movement of abutment occurs. Among them, grouting has been adopted a lot recently. In this study, analysis is carried out to review the reinforcement effect of grouting method.

In this study, the process for the cause of lateral movement of bridges is suggested. Based on the monitoring of shoe and pier movement, the lateral movement of birdges is studied. As a result, the process is applicable for the small lateral movement of the bridges.
