The Undrained Shear Strength of Overconsolidated Clays
Procedia Engineering, 2014 AbstractThe paper presents results of laboratory unconfined and confined shear tests. Tests were conducted on samples of clays taken from depth 100-300 meters below ground level. All confined tests were performed in triaxial apparatus following TXCIU procedure. Selected samples were tested in overconsolidation state.

Analysis of piezocone penetration under different drainage conditions with the two-phase Material Point Method [PDF]
, 2016 The piezocone penetration test (CPTU) is commonly used to identify the soil profile and to estimate material properties. Depending on the soil type, ranging from clay to sand, undrained, partially drained or drained conditions may occur during cone ...

Uncertainty of Mobilized Undrained Shear Strength
Soils and Foundations, 1992 ABSTRACT A method for analyzing the uncertainties involving the use of empirical relationships in design is developed. It is applied to evaluate the reliability of the relationship su(mobilized)=0.22σ’p(measured), whereby the pertinent uncertainties are analyzed using extensive laboratory and field observed data. On the average, the relationship su (

Undrained Shear Strength of Frozen Unsaturated Silts
E3S Web of Conferences, 2023 This study focuses on investigation of the undrained shear strength of unsaturated frozen silts prepared at varying initial thermal and hydraulic conditions. The initial degree of saturation controls ice and unfrozen water contents at temperatures below depression point.

Anisotropic creep model for soft soils [PDF]
, 2008 In this paper a new anisotropic model for time-dependent behaviour of soft soils is presented. The formulation is based on a previously developed isotropic creep model, assuming rotated Modified Cam Clay ellipses as contours of volumetric creep strain ...

Strength Improvement of Soft Soil Treated Using Stone Columns [PDF]
Engineering and Technology Journal, 2015 A total number of 12 models tests were carried out on models of soft clays of different values of undrained shear strength varying from 8 to 18 kPa. The tests consist of twelve models of stone columns, single column, two-column group, three-column group,
