Failure Analysis & Rehabilitation

Failure Analysis & Rehabilitation

Geocomp assesses the changes in soil properties and geological conditions at the site in order to identify the causes of the failure and make rehabilitation recommendations. Causes of failure often include excessive excavation, violation of construction procedure, generation of excessive pore water pressure by earlier piling work nearby, and sudden water-level fluctuation in front of the slope.

Katrina Litigation

Katrina Litigation, New Orleans

Dr. W. Allen Marr provided pivotal expert witness testimony, regarding the cause of floodwall breaches that caused inundation of the News Orleans Lower Ninth Ward.

Geocomp engineers assisted Dr. Marr in his evaluation with extensive analyses of global stability groundwater flow and deformations caused by the hydraulic loading of the flood wall. The work involved an extensive, collaborative site investigation and testing program to define the physical and mechanical characteristics of the soils in the EBIA.

The Colony at White Pine Canyon

The Colony at White Pine Canyon, Utah

Geocomp provided a systematic approach to evaluate the condition of all the retaining walls focusing on determining the thickness of the wire and evaluating the corrosion degradation rate. Statistical analyses from the data and reliability analyses are used to understand failure and predict remaining wall life. A program of linear polarization measurements has been initiated to help establish project specific corrosion rates over the long term.

Chicago's TARP Tunnel

Chicago's TARP Tunnel, Illinois

Geocomp analyzed and determined that excessive loads on concrete cars for the work at the Chicago's Tunnel and Reservoir Plan (TARP) tunnel project were causing tire failure and posing a major threat to project schedule and cost. Geocomp installed strain gauges on the wheel supports which indicated overload and caused failure of the wheels. Geocompss finite element analysis (FEA) resulted in the development of a revised wheel geometry and polyurethane molding process.

Mechanically Stabilized Earth Wall Study

Mechanically Stabilized Earth Wall Study, Massachusetts

The objective of NCHRP Project 24- 22 was to develop selection guidelines, soil parameters, testing methods, and construction specifications that will allow the use of a wider range of reinforced fill materials within the reinforced zone of mechanically stabilized earth (MSE) walls. Geocomp, after conducting a survey of MSE wall practices, provided recommendations to revise current AASHTO specifications to include use of backfill materials with “higher” fines.
