摘要：	The entire Bridge is supported on bearings. The bearing system of the bridge is carefully selected to take care of large compressive and tensile loads to be transferred to the foundations and also to allow for large displacements and rotations both during the construction stage and service stage. Special large size spherical bearings were provided for transfer massive load transferred from the pylon to the foundation. These bearings are fixed bearing, allowing for displacement sonly during the erection stage. Specially designed Pendulum Rocker bearing was provided to transfer large tensile loads transferred from back stay anchorages to the foundations at the same time allowing for large movement and rotation during the erection and service conditions. Guided bearings were provided at both ends of the bridge in the central axis to allow for longitudinal movement of the deck both during construction and service stage, while restraining the lateral movements. Spherical bearings with provision for longitudinal displacements are provided at the pier locations, with largest displacement requirements at the end pier locations, to take care of the large longitudinal movements of the deck both during the construction and service conditions.
