... The distributions of volume change and particle breakage within specimens were compared for uniform sands in drained triaxial tests with and without lubricated end platens. The results showed that the volume change at failure, either dilation or compression, of the sands was slightly higher...

... The drained stress-strain, volume change, and strength behaviors of sand with cross-anisotropic fabric were studied in triaxial compression tests. Dense specimens with square cross-sections, height-to-diameter ( H/D ) ratios of 1.0 and 2.5, and lubricated ends were employed. Specimens consisting...

... In this paper, the law of generation of pore-water pressure in saturated dense sands under uniform cyclic loadings has been studied. Specimens of Cheng-te fine sands with relative density D r = 0.77 have been tested in a dynamic triaxial apparatus of electromagnetic type under different...

... sands on the pore pressure induced by cyclic loadings with different densities are discussed. A procedure for evaluation of the degradation in strength and lateral resistance, which takes both the pore pressure and density into consideration, is suggested. earthquakes lateral forces pore...

... The results of a series of self-boring pressuremeter tests (SBPT) carried out in the quaternary Po river sand are presented. Assessment of total horizontal in situ stress, shear modulus and shear strength, of the tested sand is discussed. Comments on the use of the above mentioned parameters...

... specified for the top of the heliostat foundation. Soils at the site are medium dense to very dense sands and gravelly sands. Because little data were available to predict lateral deflections of drilled piers under low-level cyclic loads, a full-scale load test program was undertaken to obtain the necessary...

... A lateral-load test was conducted at an offshore site on two 1.22-m-diameter drilled shafts penetrating through 13.1 m of dense sand overlying clay. The lateral-load test was conducted by pulling the two shafts toward each other under a specified lateral load and then relaxing the load to zero...

... A large portion of the Mediterranean coastal plain of Israel is overlain by thick deposits of calcareous sands, sometimes cemented to varying degrees and forming a cemented sand known locally as kurkar. The paper presents a review of the geotechnical properties of these deposits, and methods...

... A series of tests were conducted on sands to determine the value of the coefficient of earth pressure at rest ( K 0 ) and the factors which influence its magnitude. Four laboratory techniques were used to determine the value of K 0 and the stress-strain relationship for Reid-Bedford sand...
