Abstract

The Puerto de Santa Maria and Puerto Real news highways are 17.4 kms. long, of which about 9 kms. run through a marshland area. The soft soil surveys involved piezocone reconnaissances and the construction of 3 experimental embankments. The embankments rest on ground improved with vertical drains for heights between 2.5 and 4.0 m., and with gravel columns for heights between 4.0 and 9.0 m. Expanded polystyrene was also used, for the first time in Spain, as a light fill in the embankments providing access to one of the bridges. The foundations for the 9 bridges located in the marshland were large diameter, precast, driven pier-piles (Raymond type). Embankment settlement was monitored and controlled by continuous settlement measuring lines. Pile driving was also PDA controlled.

Soil and Site Improvements of the Marsh Soils in Puerto De Santa María Highway (Cádiz, Spain)

St. Louis, Missouri

The Puerto de Santa Maria and Puerto Real news highways are 17.4 kms. long, of which about 9 kms. run through a marshland area. The soft soil surveys involved piezocone reconnaissances and the construction of 3 experimental embankments. The embankments rest on ground improved with vertical drains for heights between 2.5 and 4.0 m., and with gravel columns for heights between 4.0 and 9.0 m. Expanded polystyrene was also used, for the first time in Spain, as a light fill in the embankments providing access to one of the bridges. The foundations for the 9 bridges located in the marshland were large diameter, precast, driven pier-piles (Raymond type). Embankment settlement was monitored and controlled by continuous settlement measuring lines. Pile driving was also PDA controlled.
