Rock-steady Railway: Stabilization Method Draws on European Experience

This article describes a geotextile-encased column (GEC) system for supporting embankments under roads and railways. The system has been used in Europe, but this article describes its use in Oakland, California to repair an uplifted section of railway. A GEC is described as a 24- to 30-inch-diameter column of sand or gravel, which is sunk between 15 and 40 feet into the ground and encased in a sock constructed of geotextile fabric. It is an alternative to stone columns for use in supporting railroads or highways constructed over highly compressible soils. It can be 30 percent less expensive than alternatives. The article describes in detail how GEC was used in the Burlington Northern Santa Fe Railway grade in Oakland.
