Design and Testing of a Synthetic Clay Soil
A synthetic clay soil mixture was designed and fabricated to comply with similitude requirements set forth in a dynamic scale-model pile group foundation test. The prototype soil was a stiff, fissured, overconsolidated clay soil at the University of Houston Pile Test Facility. The dynamic response of the model soil was determined through testing by resonant column/torsional simple shear methods ...

Polymer Concrete for Structural Restoration and Corrosion Protection of Concrete Support Columns
Introduction A large copper mine and refinery in the western United States had a dilemma. Their cell house, which contains over 1,500 cells, each holding more than 20,000 gallons of electrolyte, had experienced severe corrosion and structural degradation of the support columns for the tanks. These columns support the cells in their solvent extraction and electrowinning process. This process ...

MASW and resistivity sounding case study
Anclote Natural Gas Conversion Project, Pasco County, FL Our client was coordinating the conversion of an oil-burning power plant to natural gas. As part of the associated geotechnical study, GeoView, Inc. was tasked with determining the S-wave velocity and vertical resistivity structure at the site. For the seismic portion of the study, MASW (Multi-channel Analysis of Surface Waves) and ReMi ...

Determining the design of Buried foundations case study
Foundation Mapping Determining the three-dimensional design of foundations for telecommunications towers, buildings and road signs can be impractical and sometimes nearly impossible using conventional means. Properly applied geophysical test methods, hand probing and shallow test pits provide a very cost-effective and non-destructive approach to determining the design of foundations. GeoView has ...

Detailed Introduction of Steel Frame Structure
Steel frame structure refers to a structural system that uses beams and columns to support load-bearing and resist lateral forces in the longitudinal and transverse directions. It is generally applicable to small low-rise buildings and large high-rise buildings. And because steel is a very strong building material, steel frame structure is the first choice for factory buildings, warehouses ...

Bali’s first modern landfill design case study
Bangli Regional Landfill in Indonesia’s Bali province is located about 60km outside of Denpasar, the provincial capital and home to more than 500,000 residents. The region hosts Ngurah Rai International Airport—the main entry point into Bali—and numerous tourist destinations along Bali’s popular white sands beaches. When the Indonesian central government approved ...

Donzi landfill expansion using stratagrid case study
Background The Donzi Lane Landfill in Atlanta, GA had been in use since the 1970's for construction and demolition waste disposal. The site was nearing its capacity and additional landfill space was urgently needed due to the accelerating population growth and waste stream generated by development. Due to the high cost and long lead times for designing, permitting and constructing new landfills, ...

The Basics of Slope Stability Analysis for Geosynthetics
Slope stability analysis is vital to preventing slope failures in a variety of engineering applications including landfill design, roads, dams and embankments, to name a few. Proper analysis anticipates both natural and manmade slopes and failure of foundations and retaining walls. This blog covers the necessity of slope stability analysis, how to conduct the analysis and the role of ...
