Soil Mechanics Laboratory. Soil
description and classification systems. Methods for obtaining soil
samples. Index property tests for water content, particle-size
distribution, and plasticity characteristics. Engineering parameter tests
for permeability, one-dimensional compressibility, shear strength,
compaction characteristics, and California Bearing Ratio.
Three-hour
laboratory. Spring (Cr.1)
Corequisite:
CIVL 308.
Course
Goals:
-
Introduce
the student to the visual appearance and basic behavior of particulate
materials, and illustrate key behavioral differences between
particulate and solid materials.
-
Introduce
the student to the use of soil as a civil engineering material.
-
Illustrate
various abstract theoretical concepts such as fluid flow and
development of a quick condition, one-dimensional compressibility and
shear strength that are presented in the co-requisite lecture course (CIVL
308 - Soil Mechanics).
-
Educate
students about the role that geotechnical laboratory testing plays in
geotechnical engineering design practice and engineered construction
quality control and assurance.
-
Educate
students how to prepare one type of civil engineering professional
work product (laboratory report).
Course
Objectives:
The
student will be able to:
-
Perform
index-property tests on a soil specimen and use the results to
classify the soil in the AASHTO and USCS systems and describe it using
the Modified Burmister method.
-
Calculate
the coefficient of permeability from physical testing.
-
Plot
and interpret oedometer-test data for compressibility characteristics
(RR, CR), yield stress and coefficient of consolidation.
-
Plot
and interpret simple triaxial-test data for drained and undrained
Mohr-Coulomb shear-strength parameters.
-
Plot
and interpret Proctor compaction test data for maximum dry unit weight
and optimum water content.
-
Plot
and interpret CBR test data for CBR.
