Ground Modification Techniques for the Christina River Bridge Approaches
The Christina River Bridge is a three-span bridge about 143.3 m long and 13.7 m wide. The project site was contaminated with heavy metals. The west approach for the bridge is located over an old buried stream/canal and the elevation is near EL +3.048 m, the elevation at the east approach is near EL+1.52 m. The subsurface soils consisted of a thin crust of fill underlain by as much as 12.19 m of very soft, highly-plastic silt and clay. Geotechnical design challenges included global stability, long-term settlement, and downdrag on the bridge foundation. The proposed design treatments included expanded poly-styrene retaining walls along the west approach, ground modification using deep mixing methods (DMM) along the east approach adjacent to the bridge and surcharge and quarantine of the easternmost portion of the embankment. The contractor proposed using controlled modulus columns (CMCs) in lieu of DMM to save time.
