2~(nd) Nile Bridge at Jinja, Uganda – Independent Design Check

摘要

The 2~(nd) Nile Bridge at Jinja, Uganda will be built across the River Nile in order to relieve trafficrnfrom the deteriorating existing crossing. The new bridge will be a cable stayed bridge with a 290 mrnlong main span. The cellular concrete deck will be supported by a central plane of multi-strand stayrncables from inverted Y-shaped concrete pylons incorporating steel anchor boxes.rnDesign studies included a geotechnical site investigation and a search in the surrounding area tornfind materials suitable for concrete aggregate and for construction of the approach roads. Windrntunnel tests were undertaken in Korea. The Independent Design Check was carried out concurrentlyrnwith the Final Design so as not cause delay to approvals. Project specific design criteria wererndetermined to supplement and enhance those in the local design standards, including the use ofrnEurocode traffic load models, in conjunction with design to methodologies from British Standards.rnThis paper describes the design process and the Independent Design Checking work performed tornreview and verify all structural and geotechnical aspects of the design.
