Drift of Flush-Mounted Pressure Cell Readings
Readings from earth pressure cells that were flushmounted in an instrumented retaining wall exhibited progressive change with time (drift) after backfill placement. The test procedures and conditions precluded the possibility that temperature effects could account for the drift. A series of experiments showed that the drift was caused by moisture migration from the backfill to the concrete ...

Raising awareness on materials recycling using undergraduate engineering research
Undergraduate research in engineering was used as a means of raising awareness on materials recycling and alternative recycled material products and processes. Over a three-year period, the authors hosted undergraduate researchers to work on rubber and polymer concrete, rubber-sandwich structures and recycled rubber materials for road embankments and retaining wall backfills. This paper discusses ...

Location Slidell, LA Unit C-3315 and C-4315 Project Retaining wall The beauty of living in waterfront areas comes with the danger of floods from seasonal hurricanes and tropical storms. It is important, therefore, to build above the designated flood-elevation plain. A product is sometimes needed to elevate a property, by use of mass-gravity retaining walls. At the site in Slidell, LA, the ...

Analysis of MSE Retaining Wall - Case Study
Project Description A section of retaining wall H on Trunk Highway 41 (TH41) south of the junction with TH212 in Chaska, Minnesota, "pushed out" following significant rainfall during construction. The rainfall event occurred prior to the pavement placement with the fill material exposed. The movement (horizontal displacement) of the wall that occurred after the rainfall event was permanent and ...

Phoenix park, Kangwan-do, Korea - Case Study
Perched on top of a mountainous area in Kangwon-do, Korea, the Phoenix Park Resort is protected from the effects of erosion by a system of walls including the largest retaining wall in Korea. The mountainous location of the resort makes it a favorite destination of tourists and vacationers, but the rugged terrain demanded the wall have several key characteristics: First, it had to be durable. ...

Reliability of Quary Walls Using Finite Element Analysis
During the last years the Finite Element Method (FEM) is increasingly applied in the design of quay walls. Especially in case of quay walls with relieving floors and bulk-storage as surcharge load, sub-grade reaction models are limited in their accuracy of modelling the situation. The Finite Element Method often is the only option to more detailed design calculations of quay walls. In the recent ...

Pace properties case study
Background Available property for development within the Interstate 285 perimeter in Atlanta is becoming increasingly scarce. A northwest portion of metropolitan Atlanta was becoming progressively more congested and sites previously considered too expensive or difficult to build upon were being targeted for development. The owners wanted to develop this site for a motel/suites facility to ...

Stabilization of a slope with a steep inclination due to the enlargement of a peripheral road - Case Study
The challenge The enlargement of the road needs to dig the mountain that leads to the formation of very steep slopes. The terrain consists of Marl and unstable materials and because of its exposure to humidity, has endured frequent landslides. Slope with a steep inclination - Slope with a steep inclination and Landslide The Solution To stabilize the upper layer of the slope with ...

Schlitt services seawall, Vero Beach, Florida - Case Study
One example is when prime real estate, which is scarce in south Florida, forces developers to reclaim low-lying land for commercial use. Louis Schlitt, a Vero Beach area real estate developer, approached us with such a land reclamation problem. The property slated for commercial development butted up against a saltwater estuary. In addition to the existence of agency-protected species of ...

Retaining wall for Riverbank Protection (Rio Guayabo, Panama) case study
Background: The strong currents of the famous rebel Guayabo River at it’s highest point in the Anton Valley watershed almost destroyed a large area of privately owned land. Constant changes in the water levels has eroded the banks, causing ancient trees to fall helpless into the river’s grasp. The construction of luxury residences “Los Portales” was suspended as the fight ...

Erosion control and slope stability project case study
The steep un-vegetated slope at this lakeshore residence was eroding into the lake with every rain event. Record high lake levels combined with wave action eroded the base of the hillside causing severe hillside instability. During heavy rainfall events more and more of the hillside slipped into the stairwell and lake. The residence owner was concerned with preserving the slope, overlook ...

Drainage System Stabilization Project case study
In 1997, a residential development was built upslope from this golf course drainage ditch. It began to erode, but because the ditch was filled with invasive species such as Blackberry and Reed Canary Grass, the erosion was not visible. When the non-native plants were removed to create a new golf course hole, the erosion was evident – in some places more than four feet deep, all the way ...
