Because of the use of this bridge for a long time, and the design and construction information about this bridge construction are incomplete, its abutment foundation are required to be detected to verify some concrete data and information about this bridge: the form and size of the foundation, actual state of scour for the foundation etc.
In order to analysis and calculation of the maximum transverse displacement of the top of pier caused by overturn of the pier body which resulted from scour for foundation base, calculation method under the condition of worst loading combinations will be adopted for this finite element method.
