 COURSE DESCRIPTION

This course provides advance knowledge of and application in civil construction work. The course improves capability to decide type of foundation suitable for the sub soil strata existing at construction site. Provides knowledge to calculate earth pressure and bearing capacity required for the design of sub structure for Civil Engineering Projects.

COURSE OBJECTIVES

  1. To understand the design aspects of foundation.
  2. To evaluate the stress developed in the soil medium.
  3. To understand the framework of soil investigation.

COURSE OUTCOMES

On completion of this course, the students will be able to

  1. Comprehend and utilize the geotechnical literature to establish the framework for foundation design.
  2. Plan and implement a site investigation program including subsurface exploration to evaluate soil/structure behavior and to obtain the necessary design parameters.
  3. Carry out slope stability analysis for various fills and slopes.
  4. Determine allowable bearing pressures and load carrying capabilities of different foundation systems.
