Design standards No. 13 : Embankment Dams. Chapter 12 - Foundation and Earth Materials Investigation

This existing chapter within Design Standard 13 was revised to include: Updated chapter content to reflect modern investigations practice; Added content and/or detail describing guidelines for photogrammetry, drilling and sampling in embankment dams, borehole optical televiewer imagery, Becker Penetration Tests, and care, retention, and disposal of drill core and samples; Added figures, photographs, tables, and appendices; Updated references.

This chapter of the Design Standards describes exploration and sampling procedures for investigations of new dams, existing dams, and borrow materials. Investigations of existing dams may be made for the purpose of dam safety evaluation or modification design and construction. Borrow investigations may be made of proposed construction materials in the vicinity of the dam or proposed dam. Since a great amount of information specific to foundation and earth materials investigation is presented in detail in various publications, only a brief review of these topics is given here, and those publications are referenced.
