CONTOH SOAL<br />
Tegangan Total<br />
σ = γ d,1 . h 1 + γ t,1 . h 2 + γ t,2 . h 3<br />
σ = 13,1 . 2 + 18 . 2,5 + 19,8 . 4,5<br />
= 160,3 kN/m 2<br />
Tegangan Air Pori<br />
u = γ w . (h 2 +h 3 )<br />
u = 10 . 7<br />
= 70 kN/m 2<br />
Tegangan Efektif<br />
σ’ = σ - u = 90,3 kN/m 2<br />
σ’ = γ d,1 . h 1 + (γ t,2 - γ w ) . h 2 + (γ t,2 - γ w ) . h 3<br />
σ’ = 13,1 . 2 + (18-10).2,5+(19,8-10).4,5<br />
= 90,3 kN/m 2
