WebSeveral series of uni-directional and multi-directional cyclic simple shear tests under undrained condition were carried out for normally consolidated Kaolin. From the test results it is shown that the accumulation of pore water pressure and the post-cyclic settlement increase with the shear strain amplitude and the phase difference. WebIn this study, the unconfined compressive and cyclic behaviors of saturated mucky silty clay from the reclamation area of Dalian, which has two different clay contents, are investigated using the static and dynamic triaxial test systems. The influence of clay content on the residual strain and residual pore water pressure of undisturbed and reconstituted …
Webturbed to the remolded shear strength of a soil and thus expresses the loss of strength when a soil is remolded. A variety of clay deposits may exhibit sensitivity, but some marine clay deposits exhibit very high sensitivity and very low re-molded shear strength. Such deposits are termed quick clays, which is a direct translation of the WebDec 15, 1991 · It was indicated from the test results that cyclic strength of underconsolidated clay was more uniquely defined by the degree of consolidation in terms of effective …
