The construction of the rail line required creating fill zones through natural gullies which carry water at various times of the year. The quality of backfill material, compaction effort and water management through the two sites were likely insufficient to create a stable fill zone. These factors have likely contributed to the surficial movement of soil as observed onsite.
Geostabilization International constructed two Geosynthetically Confined Soil (GCS) walls to bring the toe elevation up with the intent of reduce the slope angle to less than 30 degrees. The site was extremely challenging in terms of access to the work area, working adjacent to a watercourse and an active rail line. Our team completed the project ahead of schedule and on budget.
In the Mid-Atlantic Region of the United States a rockslide occurred that presented a variety of problems for the state’s Department of Transportation (DOT).
