Crewe Green Link Road Underbridge - Tackling complex foundation analysis using first principles

摘要

The Underbridge is a key feature of the Crewe Green Link Road South, which lies approximatelyrn2km south-east of Crewe in Cheshire. The road is a 1.1km long standard two lane dual carriagewayrnrunning south to north from the A500 roundabout towards the A5020 roundabout. It passesrnunderneath the Kidsgrove to Crewe South Railway line, which is supported on a 4m highrnembankment, hence the need for the bridge. Project challenges and site constraints led to anrninnovative solution for the design of both the bridge and its foundations. This paper shows howrnfirst principles were used to form a robust but flexible concept design that struck a good balancernbetween innovation and project risk. The methodology adopted facilitated the collaborationrnbetween all project stakeholders and led to the successful conclusion of the project in Decemberrn2015.
