CE 250: Soil Mechanics and Foundations
Catalog Description:
Soil properties, tests, classification. Analysis of soil stresses, consolidation, shear strength, lateral pressures, and ground water movement. Related design consideration involving spread footings, piles, retaining walls, and slopes. Use of programmable scientific calculator required.
Prerequisites/Corequisites:
CE 20, CE 150, ENGL 1 and CE 102 (may be taken concurrently)
By Topic: Computer applications including word processing and spreadsheets; fluid mechanics; basic writing skills; and procedures in conducting laboratory experiments.
Textbook and Other Required Material:
B.M. Das (2002) Principles of Geotechnical Engineering
J.E. Bowles (1992) Engineering Properties of Soils and Their Measurement
Course Objectives:
The objectives are to: - provide students with a general understanding of the nature of soil and rock; where it came from and how to classify it for engineering purposes.
- improve student knowledge of common soil mechanical properties.
- develop student understanding of the distribution of stresses within soil masses both from self weight and externally applied loads.
- introduce the mechanics of the movement of water through soil (seepage and consolidation)
- present the basic concepts of the design basic soil related structures.
- improve student familiarity with laboratory procedures, methods for clear reporting of experimental procedures, and evaluation of experimental results.
Topics Covered: - Origin of Soil and Grain Size
- Weight-Volume Relationships, Plasticity and Structure of Soil
- Subsoil Exploration
