Can you please give me the past year question papers of Orissa University of Agriculture and Technology, Civil Engineering, Geotechnical Engg, 6th Sem Exam?

As you want to get the past year question papers of Orissa University of Agriculture and Technology, Civil Engineering, Geotechnical Engg, 6th Sem Exam so here is the information of the same for you:

Some content of the file has been given here:

SECTION-A

Q1) (10X2=20)
a) Given: e(void ratio)=0.86, w=28%,G=2.72 Calculate ?bulk and ?sat.
b) If at e=o.4, k(co-efficient of permeability) =0.001 cm/sec. Then, at e=o.6, k=?
c) Given: H=2m, Cv=0.00002 sq.cm/sem. (double drainage) How long it woll take to attain half of the total settlement?
d) If G=2.68, w=17%. Calculate theoretical maximum dry density.
e) A soil sample consists of Gravel 30%, sand 40%, silt + clay 30%.LL=33%, PI=12%. Write down soil classification as per 1498-1970.
f) Define critical hydraulic gradient.
g) Give the statement of Darcy’s Law.
h) Write down particle size ranges of sand, silt and clay.
i) What is earth pressure at rest? Define it.
j) Define over-consolidation ratio.

SECTION-B

(attempt any four questions ) (4X5=20)
Q2) Differentiate between:
(a) Standard and modified Proctor tests for compaction.
(b) Compaction and Consolidation.

Q3) The following data are given for a soil sample. Porosity = 0.45, Sp.Gr of soil solids = 2.68, Moisture content = 10%. Determine the mass of water to be added to 10m³ of soil for full consolidation.
Q4) The time required for 50% consolidation of 25mm thick clay layer (double drainage) in the laboratory is 2 min 20 sec. How long (in days) will it take for a 3m thick clay layer of the same clay in the field under the same pressure increment to reach 50% consolidation? In the field, there is a rock layer at the bottom of the clay.
Q5) Enumerate and briefly explain the factors affecting permeability of soils.
Q6) Differentiate and compare Rankine’s and Coulomb’s theoties of earth pressure.


SECTION-C

(ATTEMPT ANY 2) (2X10=20)
Q7) Derive Terzaghi’s differential equation governing one-dimensional primary consolidation.
Q8) A retaining wall 6m high with vertical back supports a cohesive backfill having unit weight 18Kn/m³, apparent cohesion 26 Kn/m² and angle of internal friction zero. Calculate.
(a) Internal pressure intensity at the top of the wall.
(b) Depth of tension crack.
(c) Lateral pressure intensity at the base

Q9) Write short notes on the followings;
(a) Quick sand condition.
(b) Drainage conditions in shear strength tests.
