Question
Transcribed Image Text:The sub-surface profile at a certain site is shown in Figure. Given that YSM =112pcf, YML =109pcf, /ML,sat =113pcf, lateral earth pressure coefficient at rest K₁ =0.54. Compute
U, Ox, Oz, Ox', andoz at Point A.
Solution:
Total vertical stress at A: O₂ =
• Pore water pressure at A: u =
• Effective vertical stress at A: 0₂
●
