Advanced Soil Mechanics Braja M Das Solution Manual

[Eilene Balque]

Nowin its fifth edition, this classic textbook continues to offer a well-tailored resource for beginning graduate students in geotechnical engineering. Further developing the basic concepts from undergraduate study, it provides a solid foundation for advanced study.

This new edition addresses a variety of recent advances in the field and each section is updated. Braja Das particularly expands the content on consolidation, shear strength of soils, and both elastic and consolidation settlements of shallow foundations to accommodate modern developments.

This text can be followed by advanced courses dedicated to topics such as mechanical and chemical stabilization of soils, geo-environmental engineering, critical state soil mechanics, geosynthetics, rock mechanics, and earthquake engineering. It can also be used as a reference by practical consultants.

A research-based thesis course that offers students the opportunity to work on a comprehensive, individual project that demonstrates mastery of interaction design and/or design computing. Topic to be agreed upon in consultation with a department-approved supervisor. The thesis work will be of suitable complexity for results to be published and/or presented to an expert audience. Pre-requisite: DCEE Departmental authorization. 3 semesters @ 6, 12, 18 credits, respectively.
