Coduto, Foundation design: Principles and practices , Prentice-Hall, Upper Saddle River, New Jersey, 2001. http://www.prenhall.com/coduto Donald P. Coduto, Geotechnical Engineering: Principles and Practices , Prentice-Hall, Upper Saddle River, New Jersey, 2001. http://www.prenhall.com/coduto Course Learning Objectives: By the end of this course... " You will know how to do the geotechnical design of the most common types of foundations and earth structures. " You will understand the fundamentals of soil behavior as they relate to foundations, retaining structures, and embankments. Requirements: Homework & Quizzes 25 % Homework: 160pts, Quizzes: 40pts Examination 1 20 % Examination 2 20 % Final Examination 35 % Learning objectives and outcomes Assessment
- Knowledge and comprehension of geotechnical engineering vocabulary and concepts Quizzes a) Knows and can recall definitions of words at the ends of text chapters b) recognizes and can explain words at the ends of text chapters
- Application of geotechnical design principles with calculations Homework Examinations a) Can use SPT and CPT results to estimate soil strength b) can compute the factor of safety for the stability of a clay slope by using charts, with appropriate adjustments c) can compute the factor of safety for the stability of a slope using the ordinary method of slices d) can compute the earth pressures against a concrete retaining wall due to soil weight, water pressures, and surcharge loads, by using both equations and charts
e) can estimate appropriate soil characteristics for use in determining earth pressures against a wall f) can evaluate the external stability of a concrete gravity or cantilever retaining wall g) can evaluate the internal and external stability of a mechanically stabilized earth wall h) can estimate passive earth pressures and use them to evaluate wall stability i) can compute bearing pressures beneath a footing j) can compute the bearing capacity of a footing, including the effects of depth, width, load eccentricity, load inclination, and footing shape k) can estimate appropriate strength and stiffness parameters for footing design from the result of SPT, CPT, and plate bearing tests l) can estimate the distortion settlement of a footing by using both the Skempton and Schmertmann methods m) can find the required size a footing foundation, accounting for both strength and settlement concerns n) can estimate the toe bearing and side friction capacities of a single piles using the Kulhawy, alpha, and effective stress methods o) can numerically estimate pile settlement by using t-z curves p) can compute earth pressures for braced excavation systems q) can estimate the stability of a braced excavation Homework Grading Numeric scores will be assigned on each homework assignment, based on the following approach. Proper use of equations and correlations 50% Accuracy 25% Presentation 25% Guidelines a. You are encouraged to work independently, but if you do work with others, give them credit on the first page. Failure to give credit is discourteous and will be penalized 25%. b. Homework is due at the beginning of class. Late homework will not be accepted. c. Every homework assignment will count toward the final grade. d. Include a cover page with each homework set. e. Use either square grid engineering paper, blank (white) paper, or recycled paper. f. Include a cover page with each homework set. g. Print on only one side of the paper.
