The total stress paths corresponding to different loading conditions, for a soil specimenunder the isotropically consolidated stress state (O), are shown belowStress PathLoading ConditionOPI-Compression loading(σ_{1}- increasing; σ_{3} - constant)OQII-Compression unloading (σ_{1}- constant ; σ_{3} - decreasing)ORIII- Extension unloading (σ_{1}- decreasing; σ_{3} - constant)OSIV - Extension loading (σ_{1} -constant; σ_{3} -increasing)The correct match between the stress paths and the listed loading conditions, is

Question

Examsnet · Accepted Answer

Correct Answer is : OP−IV,OQ−III,OR−I,OS−II

Stress Path	Loading Condition
OP	I-Compression loading(σ1− increasing; σ3 - constant)
OQ	II-Compression unloading (σ1− constant ;σ3 - decreasing)
OR	III- Extension unloading (σ1− decreasing; σ3 - constant)
OS	IV - Extension loading (σ1 -constant; σ3 -increasing)
