Undrained Strength And Overconsolidation Ratio Parameters Of Suape Soft Based on the laboratory testing data, a strength function with varying undrained shear strength ratios can be developed for the residual soils under the stress range anticipated for a design of a tailings dam. Results from many case histories show that for normally consolidated or lightly overconsolidated homoge neous clays of low sensitivity, total stress analysis with undrained shear strength gives a reasonably accurate estimate of immediate stability.
Undrained Shear Strength Of Unsaturated Soils Undrained Shear A number of experimental methods are described for measuring soil properties like undrained shear strength and stiffness. the document also provides correlations for estimating soil parameters based on index properties or other measured parameters.

Stability during rapid drawdown can be analyzed using two approaches; namely the “effective strength” approach and the “staged undrained strength” approach. the purpose of this illustrative example is to show how to conduct a rapid drawdown analysis using the stage undrained strength approach. This webinar about the evaluation of the undrained strength of tailings has been motivated by the results of the previous webinar on geotechnical aspects controlling the stability analysis of tailing dams.
Comparison Of Effective Stress And Undrained Strength Analysis Adapted Stability during rapid drawdown can be analyzed using two approaches; namely the “effective strength” approach and the “staged undrained strength” approach. the purpose of this illustrative example is to show how to conduct a rapid drawdown analysis using the stage undrained strength approach. This webinar about the evaluation of the undrained strength of tailings has been motivated by the results of the previous webinar on geotechnical aspects controlling the stability analysis of tailing dams. Admitting that undrained tests can not be used to determine the correct values of the shear strength parameters c and φ, they may still be very useful, because in engineering practice there are many situations in which no (or very little) drainage. The special undrained behaviour option in rs2 requires calculations that using effective stiffness parameters, with a distinction between effective stresses and excess pore pressures. As such, the authors have developed an approach to estimate the state parameter and undrained shear strength of fine tailings using both in situ and laboratory testing techniques. this paper contains a detailed description of the proposed approach and an example of its application. This document discusses drained and undrained analysis and consolidation considerations for soil mechanics. it defines drained and undrained conditions based on soil permeability and loading rates.
