Slope and Retaining Wall Evaluation and Design
According to the National Landslide Hazards Program (NLHP) administered by the USGS, landslides constitute a major geologic hazard because they are widespread and can be quite severe. They occur in all 50 states and U.S. territories and cause an average of $1 to $2 billion in damages each year. GeoStructures is experienced in the design, evaluation, and rehabilitation of a full range of earth/rock slopes and retaining systems for transportation facilities, commercial sites, and residential developments. In addition to competency in traditional limit-equilibrium analysis, our strength in soil-structure interaction modeling and use of the finite element method (FEM) enables us to gain a deeper understanding of complicated slopes and earth retaining systems.
In the area of retaining systems, our engineers were among the first in Pennsylvania (late 1980s) to design geogrid-reinforced retaining walls— structures commonly referred to today as Mechanically Stabilized Earth (MSE) walls or Segmental Retaining Walls (SRW). Our capabilities in the design of slope and retaining systems includes:
- Geogrid-reinforced retaining walls and steep slopes (1H:1V or steeper)
- Geosynthetic erosion control and vegetative mats
- Mechanically Stabilized Earth (MSE) walls
- Sheet pile walls (cantilever, braced, or with tie-backs)
- Soil nailing, soil anchors, and rock anchors
- Post and panel walls
- Rock cut slopes
- Concrete retaining walls (gravity or cantilever)
- Gabion and boulder retaining walls
- Coffer dam
