To understand the strain-dependent shear modulus and damping ratio of reconstituted pumice sand samples, a series of dynamic deformation tests was performed using hollow cylindrical torsional shear test apparatus. The effects of confining pressure level and ...

Estimating the amount of conductive and nonconductive constituents in the pore space of sediments by using electrical resistivity logs generally loses accuracy where clays are present in the reservoir. Many different methods and clay models have been proposed ...

Among soil improvement techniques used to increase strength of loose and<br>medium-dense sand deposits are the dynamic means, such as vibrocompaction and blasting. Sands often exhibit a drop in cone penetration resistance immediately after the disturbance, ...

This report uses the measured S-wave velocities for recovered core samples by Lee and others (2008) at the KC151 site, reconstituted sands by Zimmer (2003), and well-log data at the Walker Ridge and Alaminos Canyon sites acquired during JIP Leg II (Boswell ...

The contribution of transverse ribs to the soil-geogrids interaction under pullout mode has been well documented. However, the contribution of transverse ribs to the soil-geogrid interaction under direct shear mode is, at best, unclear. Consequently, this ...

<p>An experimental testing program was undertaken to investigate failure mechanisms induced by the active movement of a deep rectangular trapdoor underlying a granular soil. Reduced-scale models were tested under normal gravity as well as under an increased ...

It is well known that the foundations of the Leaning Tower of Pisa were stabilised using the method of underexcavation to reduce the southward inclination of the Tower by about 10 percent in combination with controlling the seasonally fluctuating water ...

<p>In this study, firstly, a series of field monitoring data on earth pressure in soft clay, hard clay and sand ground are analyzed respectively. In the soft clay ground, the earth pressure fluctuated with backfill grouting pressure at first, it settled down ...

<p>Samples of saturated loose sand were tested under bi-directional cyclic loading to characterize liquefaction and cyclic failure, by using an advanced soil static and dynamic universal triaxial and torsional shear apparatus.</p>

<p>Although it is known that impact compaction tests are not appropriate for granular soils, these tests continue to be widely used. Excessive settlements frequently occur in granular soils where specified field compaction is based on Standard Proctor (ASTM ...
