The technical condition of an old arch bridge is meticulously investigated to find out the defect (or poten-tial defect), damage location and development tendency of the bridge and evaluate the use function of the kind of the bridge. The main arch rings, cross beams, spandrel arches, expansion joints, abutments and other diseases are analyzed. Combination with disease situation and test results, the repair and reinforcement schemes of the bridge are explained. And some construction methods about anchor spray cement concrete, planting reinforcing bar, repair crack with epoxy mortar, expansion joints handle, etc. are introduced in detail.
