CIV 240 - Soil Mechanics
Topics include: soil origin and nature; soil density, gradation and compaction; soil water content and reaction to frost; stress distribution in soil, soil shear strength; and pile bearing strength. Laboratory instruction is based on ASTM and AASHTO specifications particularly as they are used to classify and predict soil behavior.
Prerequisite: CIV 219 Strength of Materials
2 Class Hours, 3 Laboratory Hours
Learning Outcomes of the Course:
Upon successful completion of this course the student will be able to:
- Have knowledge of soil types.
- Perform soil gradation testing and create gradation curves.
- Classify soils for engineering uses.
- Provide soil descriptions by visual and manual examination of soil samples.
- Have an understanding of basic engineering properties of soils such as Atterberg Limits, relative density, and gradation.
- Solve problems involving weight and volume relationships of soils.
- Have an understanding of soil compaction, be able to perform compaction testing in the lab, and be able to create moisture-density curves.
- Conduct field density testing by the sand cone.
- Have an understanding of the flow of water through soils and be able to conduct lab permeability tests.
- Have an understanding of the common methods of soil exploration and obtaining soil samples.
- Calculate subsurface stresses in soils.
- Calculate expected consolidation settlements in soils.
- Understand the concepts of soil shear strength.
- Perform soil strength testing by the unconfined compression test and the direct shear test, and be able to analyze the results to determine strength parameters.
- Understand the basics of shallow foundation design.
