Resources by Topic: Geotechnical

Overview

Geotechnical engineering and the related discipline of engineering geology are critical to dam safety and dam engineering. These disciplines encompass understanding and evaluation of soil and rock foundation materials for all types of dams and embankment materials for earthfill and rockfill dams. Issues to be addressed for soil and rock materials can be broadly characterized as strength, deformability, and permeability.

Proficiencies

The activities involved in geotechnical engineering and engineering geology for dam safety and dam engineering are numerous. To be proficient in this area one needs to understand and/or have experience in the following areas:

  • Field investigations, both surface and subsurface,
  • Insitu testing, including geophysics,
  • Laboratory testing, including evaluation of index properties and engineering properties,
  • Stability analysis,
  • Seepage analysis, including consideration of internal erosion potential,
  • Settlement and deformation analysis,
  • Structure foundation support evaluation,
  • Specifications for embankment materials,
  • Quality control and quality assurance during construction.
