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.

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.

Undrained Shear Strength of Overconsolidated Clay [PDF]
, 2022 It has been known for a long time now that in soft and sensitive clays undrained failure occurs apparently before the full friction angle has been mobilized. The main object of this paper is to clarify the importance of deformations in the process of mobilizing undrained shear strength.

Critical undrained shear strength of sand-silt mixtures under monotonic loading [PDF]
Earth Sciences Research Journal, 2014 This study uses experimental triaxial tests with monotonic loading to develop empirical relationships to estimate undrained critical shear strength. The effect of the fines content on undrained shear strength is analyzed for different density states. The

Testing of Undrained Shear Strength in a Hollow Cylinder Apparatus
Studia Geotechnica et Mechanica, 2015 The paper presents the results of tests performed in a Torsional Shear Hollow Cylinder Apparatus on undisturbed cohesive soils. The tests were performed on lightly overconsolidated clay (Cl) and sandy silty clay (sasiCl).

Variations of Undrained Shear Strength of EPB Mud and a Calculation Model Based on Consistency Index [PDF]
Advances in Civil EngineeringIf earth pressure balance (EPB) shields are used for tunneling in clayey soils, dispersants are often applied to condition the mud. For the conditioned mud, the undrained shear strength is a key indicator determining the shield tunneling operational ...

Correlation of undrained shear strength and CPT resistance
Periodica Polytechnica Civil Engineering, 2013 The correlation of CPT resistance and undrained shear strength of soft Holocene clays is discussed in this paper. This soil type, covering significant part of Hungary is frequently involved in different geotechnical engineering problems such as building of highway embankments.

Post-Cyclic Mechanical Behaviors of Undisturbed Soft Clay with Different Degrees of Reconsolidation
Applied Sciences, 2021 Soft soil is often subjected to cyclic loading such as that imposed during storms, under traffic, or in an earthquake. Furthermore, the cyclic-loading-induced excess pore water pressure can be partially dissipated after cyclic loading.

Analysis method for basal stability of braced excavations in clay based on undrained shear strength
Yantu gongcheng xuebao, 2020 At present, the analysis method for basal stability is mostly based on the consolidated undrained shear strength index. The method is unreasonable in theory for the soft clay and does not consider the strength of the soil above the lowest support.
