In addition, five iron tension rods are bolted through the ribs to improve the transverse rigidity of the arch. The vertically layered construction enables the arch to accommodate live loading movement in the abutments and supports without collapsing.
The use of tension rods is analogous to the transverse prestressing techniques of modern bridge design. The larger of the spandrel openings, at the shoulders of the span, are 3. The smaller ones, located closer to the quarter span points, are 2. The open spandrel design saved cu m of stone, compared with a solid spandrel.
The stone paved bridge deck slopes down from the centre at a gentle gradient of 6. By modern standards, the bridge abutments seem relatively small for a bridge of this size. Each consists of five stepped courses of stone, 1. They are connected to the feet of the arch by iron rods.
The foundations are embedded about 2m in firm alluvial sediments of loam and clay. Apparently, timber stakes were driven into the ground to reduce vertical settlement of the abutments, which have settled about 50mm overall. Wing walls constructed on either side of the abutments offer additional flood protection. Answers App. Anji Bridge Fun Facts. Name Country Email. Tailor My Trip.
