Examination of the Correlation between Shear Strength, California Bearing Ratio, and Index Properties of Fine-grained Soil
… models between CBR and shear strength of soil are based on a limited number of soil test. As the required pavement thickness is directly related to the subgrade strength, misuse of correlation could lead to poor designs in practice. The aim of this study is to examine the published …

A Fundamental Investigation of Well Injection Depth Extraction (WIDE) System Performance Aspects in Fine-Grained Soil Contaminated with Trichloroethylene
… as high as 300,000 mg/kg were detected on the soil, and concentrations as high as 475 mg/L were detected in the ground water. A 21.0 m by 18.3 m WIDE demonstration system was installed over an area that encompassed a TCE plume. The test area was divided into four quadrants and 494 PVWs were …

STRUCTURE, GEOLOGY, AND ENGINEERING PROPERTIES OF TWO CARBONATIC FINE-GRAINED SOILS
Soft, carbonate-rich, fine-grained soils are commonly found in the glaciated regions of the northern United States and throughout Canada. In addition to the high compressibility potential and low shear strength, these sediments are typically characterized by alternating layers of silts and clays as …

Measurement of electromagnetic signal velocities in saturated fine-grained soils
… signal velocity measurements are common in soil disciplines, often involving Time-Domain Reflectometry. However, Time-Domain Reflectometry measurements are of limited use where velocity is frequency dependent, such as in finegrained soils. Therefore, Quarter-Wavelength Analysis was developed …

Long-term response of soils subjected to repetitive geoenvironmental loads
… of natural and industrial processes, affect soil properties and the long-term performance of geotechnical systems. This thesis provides unprecedented experimental data and physical analyses of repetitive environmental loading cycles on geomaterials. Research tools adopted in this study …

Volume change behavior of clay soils and the effect on discrete fractures
… examines the behavior of subsurface fractures in fine-grained soil such as clays in response to changing environmental conditions. Fractures serve as conduits for moisture transfer, which can lead to substantial shrinking and swelling of the surrounding fracture boundary soils. These volume …

Rate Effects in Fine Grained Soils
The strain rate dependent behaviour of fine grained soils is an important aspect of geotechnical engineering. During dynamic or rapid events such as earthquakes and rapid pile testing, a fine grained soil will display significantly different behaviour than may be observed over the long life span of …

The impact of sample scale on the compressibility parameters of saturated fine-grained soils
… sample scale on the compressibility behaviour of fine-grained soils is crucial in many applications, such as roads, embankments and foundations. The effect of sample scale represents a challenge when obtaining engineering parameters in the laboratory compared to those obtained in the field. This …

Full Scale Static Lateral Load Test of a 9 Pile Group in Sand
… and tested for comparison to the pile group. The soil profile consisted of a top layer of sand about 2.5 meters deep underlain by alternating layers of fine grained soil and sand. Analysis was done in order to determine p-multipliers for the rows in the pile group. The pile group consistently …

Full-Scale-Lateral-Load Test of a 1.2 m Diameter Drilled Shaft in Sand
The soil-structure interaction models associated with laterally loaded deep foundations have typically been based on load tests involving relatively small diameter foundations. The lateral soil resistance for larger diameter foundations has been assumed to increase linearly with diameter; however, …

Preferential flow in vertically oriented, unsaturated soil layers
… flow and the flow of water through unsaturated soils. Unfortunately, the research has been completed by different disciplines of science and engineering, resulting in a wide range of terminology and research objectives. A field program conducted during the excavation of a large waste rock pile …

Cyclic response of Gulf of Mexico clay from the Walker Ridge
… of how their foundations and the foundation soils behave under cyclic loads. When a fine-grained soil (e.g., a soft clay) is subjected to cyclic loading under undrained conditions, its structure gets progressively destroyed. The consequences of this are a progressive decrease in the cyclic …

Evaluation of Scale Effects in Load-Displacement Response of Drilled Shafts Based on Field Load Tests
… installed in a broad spectrum of coarse and fine-grained soil types. Careful review of load test records established 612-unit side resistance curves for our evaluation with roughly 12% exhibiting a fully-mobilized load-displacement behavior. Comprehensive review of all available load test …
