Abstract: Using the energy method ，the lateral displacement at the top of the higher bridge pier is calculated and analyzed on the consideration of elastic restrictions of the rubber plate supports and elastic deformation effects of the foundation.The results of the example indicate that the effects of elastic restrictions of supports and the elastic deform action effects of the foundation should not be neglected.

Key words: higher bridge pier, rubber plate supports, elastic foundation, energy method , lateral displacement
