Excellent concept explanation.. really commendable job..

[@yawarabbas490]

Sir aap legend ho

Homework questions
Question 1 = given data
G = 2.70, e= 0.5, parallel seepage at a depth = 1.5 , i = 30 ,phi = 35 , slip plane deth to the ground = 4
Calculate FOS
Solution: step 1 calculate Yd and Ysat with the formula
Yd = GYw/(1+e) ,Ysat = ((G+e)/(1+e))Yw
We get Yd = 17.65 and Ysat = 20.92
Then calculate FOS = ((Yd*parallel seepage depth(H) + Ysat * (h) - Ywh))/(Yd*H + Ysat*h)(tan phi)/(tan i)
We get ans FOS = 08354
Solution 2: data given
Depth = 5m
i = 20 , phi = 30 ,Y = 19 kn/m^3
Calculate Fos
Use formula Fos= (C + Y*Z tan phi)÷(YZ tan i)
We get ans Fos= 1.91
Solution 3: data given
Phi = 30, C = 0, fos =2 , Ysat = 20.2 kN/m^3 , Yw = 9.81kN/m^3)
Calculate i
Solution we use formula
(Ysub/Ysat) (tan phi/ tan i) = fos
And we get i = 8.445

Home work ans
1. Fos = .835
2. Fos = 1.914
3. Beta= 8.45°
Other 2 hw also done
1. Failure occurs 1&2 layers assume depth x and compare s=tau
2.finite slope fos = c.l.r/W.xbar
Thank you so much sir for wonderful session 😊.

[@muralikarthikkuntham1185]

Studying this concept for first time but it's soo clear sir, thank u soo much sir

[@juhichaubey4735]

Home work
1.Ans=0.853
2.Ans=1.5
3.8.45°
Thanku so much sir

[@kartikeypapnoi2510]

1. FOS= .8354
2. FOS= 1.913
3. angle of inclination =8.445
Thank you Sir for explaining this topic in such an easy manner

[@nikkimenon6320]

Thanks a lot sir

[@basavarajahanchinal3206]

Sir really amazing 🙏🙏

[@AnkitSingh-vb7uw]

Excellent concept explanation. first time completely understand the concept

[@BYJUSExamPrepGateEseEEECINCS]

Glad to hear that

[@46276]

How Cohesive and pi value is considering? From where did these values comes?

[@CIVIL_ENGINEER_007]

1) required γsat..
2) FOS = 2.02
3) β = 16.1 degree

[@abhijithzx]

What about finate slope

[@subhanlucky9338]

Tqs a lot sir
