Undrained shear strength of the heavily consolidated clay
Journal Title: Annals of Warsaw University of Life Sciences – SGGW. Land Reclamation - Year 2013, Vol 45, Issue 2
Abstract
The undrained shear strength cu is considered one of the most basic parameter characterizing soils in engineering practice. The particular importance of cu is in the case of clayey soil. This parameter also is the basis for the classification of soil according to the ISO standard. The undrained shear strength usually is determined from unconfined compression test or from triaxial compression test. In the simple way it can be estimated from the fall cone penetrometer test as index parameter. In the presented work the results of unconfined compression tests for very stiff, heavily consolidated clay were shown. All analysed clay specimens were taken from the large depth, up to 303 m below terrain level. The tests results: undrained shear strength cu and unconfined compression strength qu were discussed in the relation on in situ consolidation stress, Atterberg's limits and the indicatory test - fall cone test results
