ABSTRACT
Taking the reconstruction of the abutment of a separated overpass as an example, this paper expounds the application of a new technology and the scheme optimization in the reconstruction of an existing abutment. Then the comparative analysis of the scheme optimization results is made, and then a safe, stable and economical scheme is chosen as the basis of the reconstruction. Moreover, the construction process and controlling essentials are explained, which can be regarded as reference for reconstruction of similar bridges.
