Approach to Geotechnical Characterization and Slope Design Data Acquisition Programs in Different Deposit Types

This paper will address critical aspects for consideration when characterizing parameters related to geology, structural geology, hydrogeology and rock mass for definition of geotechnical domains for slope design. The types of deposits that will be presented: general porphyry rock masses (i.e. alteration aspects, joint characterization); uniform bedded and foliated deposits (i.e. continuous structure, weak layers), tropical deposits (i.e. preferential weathering, material classification, structure aspects) and structurally-mineralized deposits. The intention is to discuss geotechnical specific attributes with consideration to each deposit type, and present a series of deposit-specific tables that highlights the more important aspects when considering the expected slope performance for design purposes. In addition, suggested geotechnical evaluation methodologies, stability assessment and broad design approaches will be included for each deposit type.
