bridge and construction process with integral pier-type mixed abutment

摘要

In as reinforced soil retaining walls and configure complex alternating bridge formed by the piers, the flexibility of the pillars of the piers in bending than the axial stiffness of the member is formed by a large reinforced concrete multi-casting ductile columns and the first and second pier coping portion annual formed of a ganggyeol structure integrating the pier and an upper girder and the upper slab and poured into ever construction method, and connect the slab even as to form as an integral to the chest wall portions of the pier construction, a conventional normal shift, integral alternately, remove the shortcomings of complex shifts and benefits are collected by, and essentially remove the bridge bearings and upper slab and expansion joints connecting the pier coping for supporting the upper girder to the pier, speed of construction of the complex shift bridges and air improve the workability and, sikimyeo while improving the structural safety and durability of bridges extending the life of the bridge, reducing also the maintenance of the bridge details, increase cost-effectiveness, and (高) securing shifts of safe is easy and the safety of the chest wall structure increase US, it improves the running properties of the vehicle for driving the bridge and can reduce the noise and, ultimately, economy and workability is excellent, yet the performance is also superior to monolithic composite shift bridge and its construction that can activate the application of the composite alternating bridge to provide a method. ; Bridges, piers, monolithic composite shifts, flexible pillars, copings, the top girder, top slab, the slab connection
