... The internal shear strength of geosynthetic clay liners (GCLs) can be evaluated through direct shear testing in accordance with ASTM D6243 under a specific set of boundary conditions for a given normal stress. In order to prevent slippage at the GCL–gripping system interface and ensure...

... Contaminated sediments, near urbanized areas, usually have a high content of organic matter and therefore a high water content and low shear strength. During dredging, additional water is mixed with the sediment, increasing the water content even further. The resulting dredged material that has...

... This paper discusses the laboratory measurement of internal and interface shear strengths of geosynthetic clay liners (GCLs). All relevant issues are addressed, including test apparatus, gripping/clamping, hydration, consolidation, shear displacement rate, and post-test measurements...

... compression test data. A simple formula is derived to relate the compressive strength to the shear stiffness, shear strength, and standard deviation of fiber misalignment. The formula is completely defined in terms of these three parameters, all of which can be measured by standard experimental procedures...

... of the high bonding, or adsorption, of the liquid phase within and around these flocs. The authors have carried out a series of tests, including consolidation and shear strength tests, in order to attempt to characterise the geotechnical engineering and consolidation behaviour of these sludges. The great...

... Peats and organic soils are encountered in many geographical areas and because of their organic solids and high water content they exhibit mechanical properties somewhat different than the customary behavior of inorganic clays. Shear strength and coefficient of earth pressure at-rest are two...

... Field vane tests were conducted on paper sludge landfill covers located in Montague and Hubbardston, Massachusetts, to measure the in-situ undrained shear strength. These landfill covers used the same type of sludge for the barrier layer, and the basic cover designs were similar. The Hubbardston...

... along the plane of segregation. This study indicated that the presence of central segregation is a critical factor to induce reduction in the shear strength. As the sulfur content goes down the segregation line disappears and the shear strength also increases. At 0.01% maximum sulfur best results...

... to evaluate shear strength, deformability, and compressibility. Mixtures made with typical backfill soils such as clean sand, sandy silt, and clay were tested. Results of the tests show that tire chips and soil-tire chip mixtures behave like soils, but are more compressible and also require more deformation...

...). The test results demonstrate that the needlepunched thermally locked reinforcing fibers provide substantial short-term shear strength to a GCL. However, there is a growing concern that the long-term shear strength of this type of GCL can be affected due to the potential of creep within the reinforcing...

... This paper provides guidelines for measuring the internal and interface shear strengths of geosynthetic clay liners (GCLs) in a direct shear test. Currently, there is significant variability between laboratories in shear testing procedures for GCLs; the major differences are related to specimen...

... Geosynthetic Clay Liners (GCLs) are being used on increasingly steep and high landfill slopes, which requires careful determination of the appropriate shear strength to be used in design. This paper reviews shear strength testing of GCLs, and the subsequent use of the strength data, from...

Analysis of the resulting data revealed that a squared stress ratio interaction curve providedsatisfactory estimates of the ultimate shear strength of a fastener shank subjected to a constant tensile load. combined loading stress ratio shear strength shear loading fastener...

... In laboratory tests such as triaxial, consolidation, and scale model tests, the laboratory specimens are often loaded at a different rate than the soil in the field. It is known that clayey soils exhibit rate dependent volume change (secondary compression) and rate dependent shear strength...

... In order to evaluate the shear strength and dilatancy behavior of coarse granular soils reinforced with geogrid a large direct shear apparatus (1000×1000×940 mm) was built. A series of shear tests were carried out to study the effect of geogrid orientation and soil volume changes on shear...

Stabilities of embankments on several composite grounds are analyzed by the proposed method in which anisotropy of shear strength parameters is Introduced. The result shows that the proposed method gives lower safety factor than the conventional method...

... simulations to the deep ocean is hindered by the lack of reliable geotechnical data for the sediments at the deep ocean study areas; for example, because no in-situ measurements have been made, shear strength data are limited to the depth of the longest cores (35 m) and their accuracy reduced...
