Abstract:
The strength and compressibility
characteristics of cohesive soil are important aspects
in foundation engineering such as the bearing capacity
of shallow foundation and piles, the stability of slopes
of dams and embankments and lateral earth pressure on
retaining walls. In this project work the strength
parameters (unconfined compressive strength and
undrained shear strength) and compressibility parameters
(compression index, recompression index and coefficient
of consolidation) to index properties (liquid limit,
plasticity index and initial void ratio) of cohesive
soil of the study area have been described graphically
and an attempt has been made to establish correlation
among strength parameters, compressibility parameters
and index properties of soil. Also the values of
strength and compressibility parameters of cohesive soil
have been furnished with lowest and highest range. These
may help the design engineer for deigning the structures
for construction in the study area. The value of
unconfined compressive strength, undrained shear
strength, N-value, compression index , recompression
index and coefficient of consolidation of cohesive soil
of the study area were found in ranges between 20 kPa to
128 kPa, 10 kPa to 64 kPa, 2 to13, 0.243 to 0.705,
0.00678 to 0.082 and 0.000714 cm2/sec.to
0.0201 cm2/sec. respectively.
