JOINTLESS BRIDGE USING DUPLICATE ABUTMENT

摘要

A double abutment and a jointless bridge using the same are provided to allow the slab to bear the torsion strain due to vibration by connecting the bottom slab and the contact slab via a dowel bar. A double abutment comprises a form(10) in which a bottom slab(1) is arranged on the top, a first abutment(20) including a support part(22) in which a plurality of insertion holes are formed in the longitudinal direction and a base part(24) connected to the upper side of the support part, a support pile(30) which is connected to the lower side of the support part of the first abutment and supports the first abutment, a second abutment(40) which is connected to the form and is located apart from the support part and the base part of the first abutment, and a flexible pile(50) which elastically supports the relative displacement delivered to the second abutment in the elastic deformation according to the temperature change of the form.
