Methods of measurement and monitoring abutments displacements

Abstract

    This paper presents the methods and solutions to measurement and monitoring displacements of abutments being applied worldwide. Abutment is a complex structure, directly under the huge load combination from the superstructure on the extraction process as well as by the pressure load of the fill behind abutment. Design of abutment is very important, because every motion and deformation of abutment will impact significantly on the structure during exploitation and operation. In the article the author introduce statistical methods of measurement and monitoring displacements of abutments in order to devise effective solutions can be applied in monitoring systems for bridge - BHMS (Bridge Health Monitoring System) to minimize the risks which may occur at the same time optimizing the maintenance maintain the works in a reasonable manner, prolonged longevity of bridges (Lương Minh Chính, 2014) (Lương Minh Chính, 2015).
