Available in PDF, EPUB and Kindle. Book excerpt: As part of its continuing program to stimulate superior basic research in the marine environment, the Office of Naval Research, Ocean Science and Technology Division, sponsored a series of closed seminar-workshops in 1972-1973. Each seminar focused upon one re search area of marine geology which is relatively new and in need of a critical evaluation and accelerated support. The subjects areas chosen for the seminars were: 1. natural gases in marine sediments and their mode of distribution, 2. nephelometry and the optical properties of ocean waters, 3. physical and engineering properties of deep-sea sediments, and 4. physics of sound in marine sediments. The objectives of each seminar-workshop were to bring into sharper focus the state-of-the-science within each subject area, to effect some degree of coordination among the investigators working within each of these areas and to provide the Ocean Science and Technology Division guidance for national program support. This volume.contains most of the papers presented at the semi nar on the physical and engineering properties of deep-sea sediments. The seminar was held at Airlie House, Airlie, Virginia on April 24- 27, 1973 and was organized and chaired by A. Inderbitzen. The at tendees were invited from among the leading investigators in this field from both the engineering and scientific disciplines. Each attendee was requested to prepare a paper within his area of spe ciality.
Download or read book DOSIST II written by H. J. Lee and published by . This book was released on 1976 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: DOSIST II (Deep Ocean Sampling and In-Situ Testing) was a cruise in the Western North Atlantic Ocean conducted to evaluate the in-place engineering behavior of several typical deep ocean sediments. In-place vane shear tests were performed, and sediment cores (gravity, piston, and box) were taken. Laboratory tests were conducted on the cored samples to classify the sediments and to determine which testing procedure best reproduces the measured in-place strength. This was found to be consolidated-undrained triaxial testing. The sediments tested in-place were a foraminifera-dominated calcareous ooze and a proximal turbidite. Both of these sediments are nearly cohesionless and retain little of their in-place strength when sampled. A deep sea pelagic clay was cored and subjected to laboratory testing, but was not tested in-place. Estimated in-place strength profiles were derived for each of these sediments to subbottom depths in excess of 50 feet (15 m).
Download or read book Direct Shear Testing of Marine Sediment written by John Stoddard Berg and published by . This book was released on 1971 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: Traditionally, the methods used to determine the mechanical properties of marine sediments were those used in the field of soil mechanics. These methods are generally acceptable when the sediment tested is plastic or at water contents below the liquid limit. However, for predicting in-situ conditions, that is for sediment at water contents above the liquid limit, the problem is complex. Specifically, the determination of shear strength of an unconsolidated-undrained sample by the direct shear method was found to exhibit an angle of internal friction ranging from 19 degrees to 23.5 degrees. This indicates that the shear strength of the sediments is dependent on the normal load applied to it. (Author).

Download or read book An Unconfined Compression Testing Machine for Marine Sediments written by Richard Karl Westfahl and published by . This book was released on 1970 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The two most common laboratory test methods used for measuring the undisturbed or original shear strength of marine sediments are the vane shear test and the unconfined compression test. The application of the load in the unconfined compression test is accomplished either in a strain-controlled or a stress-controlled manner. An unconfined compression testing machine was constructed to allow application of the load by either the strain-controlled or stress-controlled method, and it was specifically designed to accurately test marine sediments having relatively low values of shear strength. A unique feature of the apparatus is that it provides a continuous plot of displacement versus load throughout the test procedure. Tests for shear strength in the two load application modes were conducted on gravity cores taken on the continental slope between San Francisco and Monterey. Results of the tests compared favorable with each other, as well as with values secured from vane shear testing. The tests suggest that these particular sediments have friction angles approximating 30 degrees. (Author).

Download or read book A Comparison of the Test Results of Vane and Direct Shear Tests Made on Recent Marine Sediments written by A. L. Inderbitzen and published by . This book was released on 1969 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Shear strength envelopes calculated from consolidated-undrained direct shear tests (hereafter called direct-shear lines) were compared to strength envelopes calculated from vane shear tests (hereafter called vane-shear lines) made throughout the length of a sediment core. These comparisons were made on shear strength measurements from seven recent marine sediment cores. The seven sediment cores used for this study were obtained from the upper San Diego Trough slope in water depths of 249 to 291 meters by Lockheed's submersible DEEP QUEST. The materials tested were classified primarily in the clayey silt to silty clay range based upon grain size distribution. (Author).

This book was released on 1971 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: The consequences resulting from varying the parameters of the vane shear test (used to determine the shear strength of marine sediments) were investigated. Experiment showed that larger ratios of container diameter to vane diameter yield more accurate shear strengths. It was also shown that the four-bladed vane produced the best results. Finally, rates of rotation of one and two revolutions per hour were found to give accurate values of shear strength, while higher rates of rotation proved to be unsatisfactory. (Author).

This book was released on 1972 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the tasks of the Lockheed Missiles and Space Company's submersible Deep Quest has been to obtain detailed information on the strength characteristics of the sea floor. Continuing projects, carried out with a corer and a vane shear machine mounted on the submersible, are a comparison of in-place and laboratory vane shear strength values and an investigation of the lateral and vertical variability of in-place shear strength. The area being investigated for these projects is approximately 13 nautical miles southwest of San Diego, Calif., on the floor of the San Diego Trough at a depth of 4050 ft.
Download or read book Advanced Triaxial Testing of Soil and Rock written by Robert T. Donaghe and published by ASTM International. This book was released on 1988 with total page 896 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Although the triaxial compression test is presently the most widely used procedure for determining strength and stress-deformation properties of soils, there have been no books published on triaxial testing since the 1962 second edition of the landmark work The Measurement of Soil Properties in the Triaxial Test by Bishop and Henkel. It is apparent there is a need to document advances made in triaxial testing since publication of Bishop and Henkel's book and to examine the current state of the art in a forum devoted solely to triaxial testing. Because of increasing versatility brought about by recent developments in testing techniques and equipment, it is also important that the geotechnical profession be provided with an up-to-date awareness of potential uses for the triaxial test."--Overview.
