Increase in Undrained Shear Strength Due to Secondary Compression

Soils and Foundations, 1983
Undrained shear strength of clay is generally increased due to secondary compression or delayed compression. Though this increased strength is regarded as being derived from densification of clay particles and the metamorphosis of clay minerals and dissolution of cemented matters into free water, the mechanism of increase in strength during long term ...

Analysis of influence of initial shear stress on undrained instability characteristics of construction waste soil

Yantu gongcheng xuebao
The stress distribution and variation inside loosely deposited construction waste soil are highly complex. In particular, the continuous filling process alters the initial shear stress, which may significantly change the instability behavior of the waste

Rock mechanical properties under reconstructed deep in situ thermo–hydro–mechanical conditions: Implications for CO₂‐related injection scenarios

Deep Underground Science and Engineering, EarlyView.
The graphical abstract illustrates a reconstructed in situ thermo‐hydro‐mechanical (THM) framework in which porosity serves as the central variable linking stress, pore pressure, and temperature to evolving mechanical properties of rocks. Under burial conditions, in situ stress, pore pressure, and temperature jointly govern volumetric strain and ...

Seismic Fragility of Gravity and Semi‐Gravity Retaining Walls and Its Impact on the Functionality Loss of Road Infrastructures

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Retaining walls are key geotechnical components of road infrastructure, whose seismic performance directly affects the resilience of transportation networks. Despite their importance, seismic fragility models for retaining walls available in the literature refer only to specific case studies.

A Method for Correcting Undrained Shear Strength for Sample Disturbance

Soils and Foundations, 1985
ABSTRACT In order to find out an appropriate method for correcting the undrained shear strength for sample disturbance, a series of triaxial compression tests is performed on mixed soil samples having wide range of plasticity index. Conditions of the ideal and perfect samples are brought to by the K0 consolidation and the shear stress release after ...
