Cyclic strength of underconsolidated clay
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 … 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.

WebApr 4, 2024 · I have a consolidation result (Sample depth 26’, groundwater at 3’from existing grade) that shows the soil is overconsolidated with Pc=7.5 ksf. The test was performed as loading 0.1, .25, .5, 1, 2, 4, 1, .25, .5, 1, 2, 4, 8, 16, 4, 1, .25 ksf. Lab test shows soil type is CL, natural moisture 81%, PL=32, LL=91. It’s in coastal area. WebJan 2, 2024 · A large amount of data regarding the effect of cyclic loading on the strength of clay soil was surveyed by Lee and Focht [ 5 ]. It was concluded that the strength after cyclic loading was less than the static undrained strength, and that reverse (two-way) cyclic loading was more detrimental than non-reverse (one-way) loading [ 6, 7, 8 ].
WebSep 5, 2024 · The cyclic strength of clays should be distinguished from that of liquefiable soils. Conventional strain failure criteria are more suitable for clays than the initial liquefaction criterion used for liquefiable soils. Several typical strain values were used to determine cyclic strength so that the effects of various mineral compositions on cyclic WebMay 4, 2024 · In this case study, the soil improvement results and a back analysis using PLAXIS (2015) [] to compute the shear strengths of a well-documented ground improvement projects, completed in 2013 in Cotai, Macau S.A.R., is described.The project covers a total area of 220000 m 2 on a reclaimed land on marine clay undergoing consolidation. …

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 dazn fight tonight
