A simpler theoretical solution for undrained shear strength index of saturated clayey soil under arbitrary degree of consolidation is deduced by the means of stress path method in this paper.And comparision tests show that the calculated result based on theoretical formula above is in good agreement....

undrained shear strengthThe undrained shear strength of the ground at a detached housing siterncan be estimated by the unconfined compressive strength, which isrnobtained from a core sample. However, this requires considerable timernand money. Therefore, a formula, and experience, are usually applied...
From Atterberg's limit values LI is calculated, by substituting LI value undrained shear strength values are calculated using WROTH AND WOOD formula and correlations were developed between calculated undrained shear strength and SPT N. The obtained correlation is verified by comparing with previous ...
It is known that the empirical formulae to interpret CPT readings use cone factors Nk, Nkt and Nke which can be highly variable. This can lead to unacceptable error levels in the assessment of undrained shear strength (su). Nevertheless, it was noticed in this study that the undrained ...
