Earth Manual - Part 1 (Third Edition)

The manual provides technical information on the field and laboratory investigations and construction control of soils used as foundations and materials for dams, canals, and many other types of structures built for reclamation projects in the United States of America. Part 1 discusses general earth and foundation technology applicable to the construction of water resources structures. Included in Part 1 are chapters on: the properties of soils, principles and stages of soil investigations, and quality control of earth construction. The appendix contains detailed procedures for sampling, classification, and field and laboratory testing of soils.

Engineering Practice for Wetting-Induced Collapse of Soils

While not specific to tailings, this webinar includes valuable knowledge for tailings engineers. This webinar will teach you how to apply unsaturated soil mechanics for more reasonable evaluation of field collapse. It will provide you with a basic understanding of wetting-induced collapse behavior in natural and compacted soils. It will address proper sampling methods, laboratory sample preparation and testing techniques to evaluate collapse potential of natural and compacted soils. You will learn the importance of unsaturated soil mechanics in the evaluation of and solution to collapse settlements associated with embankment and foundation loading.

Geotechnical design and uncertainty in residual soil slopes, MGR 2019: Proceedings of the First International Conference on Mining Geomechanical Risk, MGR 2019

Mining in residual soils is a characteristic of some open pit mines, particularly those mines in the tropical and sub-tropical regions. With residual soils’ prevalence on the earth’s surface almost as common as that of sedimentary rocks (Wesley 2013), mining in such soils requires special understanding of the behaviour and characteristics of the residual soil to determine slope designs that are both safe and economic. Due to the presence of relict structures, and the relatively low strength of the residual soils and weathered rock, design slope angles in these materials should be developed by blending the results of the kinematic assessments of geologic structures with rock mass stability analyses and traditional soil mechanics (Newcomen & Burton 2000). It is thus imperative that geotechnical designs should be site/location-specific and based on soil’s field performance, back-analyses and risk zoning. Understanding the variability of these materials is important for developing robust designs. This paper outlines the different aspects that are to be considered when conducting slope designs in residual soils, and in particular, saprolites, and summarises shear strength data from various mine sites that highlights the uncertainty associated with these parameters.

Introduction to the Cone Penetration Test (CPT) (Webinar #1)

This first webinar will be an Introduction to CPT, and cover the history of the CPT, basic soil parameters and the soil behavior type chartsbehavior-based descriptions. The update includes a method to identify the existence of microstructure in soils. Examples are used to illustrate the advantages of such a system.
