LATERAL THINKING AT GLOUCESTER LEADS TO NEW GROUND RULES

It was anticipated that severe settlement of the roughly 8M thick layer of alluvium in the River Severn flood plain would also lead to lateral forces acting on piles supporting a new crossing of the navigable section of the river carrying the A40 trunk road away from the city centre. The embankment was formed two years early under an advanced contract. Extensive soil tests checked the decrease in shear strength, and the lateral movement, but it was found to be well within the estimated 20mm allowed in the design. Hollow U shaped bridge abutments, formed half way up the end slope of the embankment were used. Very good agreement has been found between the reassessed rate of vertical settlement and values predicted, using data on load application, by a TRRL finite element computer program. The viaduct structure has an in-situ prestressed cellular deck with pre-cast drop beams over the river. Because major plant and heavy falsework foundation loads could not be allowed on the flood plain, temporary work supports had to be separately piled and Bailey bridge sections have been used to support a complete span plus a 12M overlay.
