has been subjected to the reservoir load for a sufficiently long period.
Therefore:
The soil has had sufficient time to consolidate.
Excess pore-water pressure has had sufficient time to dissipate.
Drainage is permitted during shearing.
Hence, the stability should be analyzed in terms of effective stress parameters: c', f'
These parameters are directly obtained from the Consolidated Drained (CD) Test
Steady Seepage Condition एक long-term condition है। इस अवस्था में soil को पर्याप्त समय मिलता है जिससे:
Soil का consolidation पूरा हो जाता है।
Excess pore-water pressure dissipate हो जाता है।
Shearing के दौरान drainage की अनुमति होती है।
इसलिए analysis effective stress parameters पर किया जाता है: : c', f'
इन parameters को प्राप्त करने के लिए Consolidated Drained (CD) Test सबसे उपयुक्त है।
