Download or read book Comparison of Field Vane and Laboratory Undrained Shear Strength in Soft Sensitive Clays written by CC. Ladd and published by . This book was released on 1988 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of the paper is to compare, at two different sites, the field vane strength with the undrained shear strength measured in laboratory on intact clay specimens cut from block samples. The laboratory tests included triaxial compression, triaxial extension, and direct simple shear tests on specimens anisotropically reconsolidated to the in-situ stresses. The laboratory undrained shear strength was determined on averaged stress strain curves built from the three types of laboratory tests in order to account for strain compatibility. At both sites, the undrained shear strengths obtained by the field vane and by the laboratory tests are nearly identical. The comparison is discussed in terms of field vane correction.

Book excerpt: The field vane shear test is one of the most common in situ tests to obtain the undrained shear strength of soft clay. Uncoupling of the torque generated by the soil resistance along the vertical and horizontal planes of the vane has been done by conducting conventional direct shear test and newly developed vertical direct shear test on the soil. From the shear stress-displacement relationship of the direct shear tests, simple analysis is performed to simulate the field vane behavior at various depths. The results of the simulation agree well with those obtained from the field vane tests on soft Bangkok clay. The conventional method of computing the undrained shear strength of the field vane shear based on the maximum torque is close to the equivalent average value from the shear box tests. A special laboratory triaxial vane apparatus was also used to study the shearing behavior of the soft clay with the capability of Ko-consolidating the sample before conducting the vane shear test. The results of the triaxial vane tests were also compared with the predictions. The predicted torque values are lower than the experimental data for the same angle of rotation.

Available in PDF, EPUB and Kindle. Book excerpt: The Corps of Engineers has prepared a basic report of investigation for proposed underwater barriers in the San Francisco Bay area. In completing this study, it has been necessary to obtain soil design constants and to develop methods of analyses. This paper deals with the comparison of field vane-shear results and shear-strength constants as developed in the laboratory. The tests were conducted on soft bay mud that had been overlain for several years with a large displacement type fill.

Download or read book On the Sensitivity of Soft Clay Obtained by the Field Vane Test written by Yan-Bin Gao and published by . This book was released on 2015 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: The field vane test (FVT) is used more widely today in traditional site investigations to investigate the sensitivity of soft clay and even likely to replace the unconfined compression test (UCT). In this paper, the strengths and sensitivities of Shanghai soft clays obtained by an FVT and a UCT from a traditional site investigation and that obtained by the laboratory vane test (LVT) and the UCT on block samples were compared in detail. It was found that the FVT obtains higher strengths but lower sensitivity. This phenomenon was also observed in other soft clays. The unreliability of sensitivity determination by the FVT seems to increase with the liquid index and sensitivity of soil. The vane remolding method used in the FVT was found to be the major factor that causes these problems and cannot remold soil completely using the recommended number of vane rotations.

Available in PDF, EPUB and Kindle. Book excerpt: Undrained shear strength results from field vane shear tests are compared with those obtained from flat plate dilatometer, screw plate, pressuremeter, and piezocone tests at several sites in the lower mainland near Vancouver, British Columbia, Canada. The sites include deltaic deposits of soft organic soils, clay silts, and moderately to highly sensitive clays. The sites consist primarily of normally consolidated soils, but results in overconsolidated soils are also included. The test procedures and methods of interpretation are briefly described for each in-situ test type in addition to a discussion of the results.

This book was released on 1988 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: Site investigations were recently performed offshore at three prospective plat-form sites in water depths between 400 and 500 m in the Gulf of Mexico. Soil conditions at the sites generally range from very soft clays near the seafloor to very stiff clays at 120- to 150-m penetration. Analyses of stress history indicate the soils at these locations are generally normally consolidated. Laboratory tests were performed on recovered specimens to deter-mine the undrained shear strength. Standard laboratory miniature vane shear tests and unconsolidated-undrained triaxial tests were performed in addition to consolidated-undrained tests using stress history and normalized soil engineering properties (SHANSEP) procedures. Tests performed in the field included in-situ vane and cone penetrometer. Cone factors Nk were computed using in-situ vane shear strengths as the reference strength.

Download or read book Tropical Peatland Ecosystems written by Mitsuru Osaki and published by Springer. This book was released on 2015-12-07 with total page 633 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is an excellent resource for scientists, political decision makers, and students interested in the impact of peatlands on climate change and ecosystem function, containing a plethora of recent research results such as monitoring-sensing-modeling for carbon–water flux/storage, biodiversity and peatland management in tropical regions. It is estimated that more than 23 million hectares (62 %) of the total global tropical peatland area are located in Southeast Asia, in lowland or coastal areas of East Sumatra, Kalimantan, West Papua, Papua New Guinea, Brunei, Peninsular Malaysia, Sabah, Sarawak and Southeast Thailand. Tropical peatland has a vital carbon–water storage function and is host to a huge diversity of plant and animal species. Peatland ecosystems are extremely vulnerable to climate change and the impacts of human activities such as logging, drainage and conversion to agricultural land. In Southeast Asia, severe episodic droughts associated with the El Niño-Southern Oscillation, in combination with over-drainage, forest degradation, and land-use changes, have caused widespread peatland fires and microbial peat oxidation. Indonesia's 20 Mha peatland area is estimated to include about 45–55 GtC of carbon stocks. As a result of land use and development, Indonesia is the third largest emitter of greenhouse gases (2–3 Gtons carbon dioxide equivalent per year), 80 % of which is due to deforestation and peatland loss. Thus, tropical peatlands are key ecosystems in terms of the carbon–water cycle and climate change.
