SUMMARY:Online Workshop: Soil Nail Walls - Design and Construction
DESCRIPTION:Soil nailing technology is versatile and has been widely used worldwide over the last 3 decades for temporary and permanent excavation support. The design and performance of soil nail walls are intricately linked with their construction procedures.  To avoid adverse performance issues\, design and construction processes for a soil nail wall must be tailored to specific geometry and the environment (conditions) expected over its specified lifetime. This workshop will help participants gain a better understanding of design and construction procedures using limit-state concepts\, aligned with the latest guidelines based on the Load and Resistance Factor Design (LRFD) methodology of the American Association of State Highway Officials (AASHTO) and the Federal Highway Administration (FHWA). The contrast between LRFD and Allowable Stress Design (ASD) methodologies will also be included. Design and construction (including field testing) aspects of Solid Bar Soil Nails (SBSNs) and Hollow Bar Soil Nails (HBSNs) will be discussed. \nUsing a collaborative\, interactive learning approach\, this virtual workshop will help you understand the design and construction of soil-nail walls. You will learn new design approaches based on the LRFD platform\, which underpins the American Association of State Highway and Transportation Officials (AASHTO) and the Federal Highway Administration (FHWA) guidelines for soil nail walls. The workshop will help you assimilate the design and construction aspects through active participation by frequent interactions throughout the workshop and real-time expert feedback. These interactions will help you understand the nuances of the newer design principles and avoid costly design errors in real-world projects. Between the two live sessions\, attendees will work independently on an application (e.g.\, exercises) or a reflection (e.g.\, reading) assignment. \nSession 1 of 2 \n\nIntroductions\nTerminology\, construction steps\, applications\, and explorations\nLimit states\, load factors\, and resistance factors\nService limit state (wall movements)\nStrength and Extreme Event limit states\nLimit Equilibrium (LE) analysis software tools\nCorrosion Considerations\nFacing (shotcrete)\nReview of Session 1\nInteractive Question and Answer (Q&A) session\nAssignment of classwork\nAdjourn for classwork and break\n\nSession 2 of 2 \n\nRoadmap for Session 2\nReview of classwork assignments\nInformation for plans and specifications\nNail types and construction processes\nGrout and grouting\nNail testing and nail acceptance criteria\nClosure and References\nReview of Session 2 and full workshop\nInteractive Question and Answer (Q&A) session

SUMMARY:Online Workshop on Compaction of Soils and Engineering Properties of Compacted Soils
DESCRIPTION:In the construction of highway embankments\, earth dams\, retaining walls\, structural foundations\, and many other facilities\, loose soils must be compacted to increase their densities.  The principal objectives in compacting soil are normally to create fill of high strength and low compressibility\, and\, in the case of water-retaining fill\, of low permeability. The ultimate goal is to construct safe earth structures that can provide the desired serviceability over their design lifetimes and minimize long-term maintenance. This workshop discusses the conventional (e.g.\, Proctor) methods of compaction and alternative methods of compaction based on soil air voids and shear strength (SAV&S) principles. It evaluates applicability of compaction procedures for various soil landforms (e.g.\, residual vs transported) soils. It also discusses implications of laboratory tests on field compaction specifications and properties of compacted soils such as shear strength\, volume change\, and permeability. It evaluates the concept of cohesion component of shear strength in compacted soils. \nUsing a collaborative and interactive learning approach\, this virtual workshop will help learners understand challenges associated with specification and construction of safe and serviceable compacted soil structures that will also help long-term maintenance needs. Learn new concepts of soil compaction that builds upon your prior knowledge and through active participation you will integrate the new knowledge into your understanding. You will also generate new ideas through brainstorming and discussion and develop a better understanding of the practical methods and processes of soil compaction\, learn about real-world problems that your peers encounter on projects\, and solutions they have implemented\, and receive real-time expert feedback. In between the two live sessions\, attendees will independently work on an application (e.g.\, exercises) or a reflection (e.g.\, reading) assignment. \nSession 1 \n\nIntroductions\nTerminology and Basics of Compaction\nEffect of Unit Weight\, Voids\, and Fabric/Structure\nField Compaction Procedures\nRelative Density and Relative Compaction\nPractical Issues and SAV&S Field Control Method\nChoice of Field Compaction Control Method\n\nSession 2 \n\nReview of classwork assignment\nRoadmap for Day 2\nShear Strength Characteristics of Compacted Soils\nVolume Change Characteristics of Compacted Soils\nPermeability Characteristics of Compacted Soils\nProof-rolling\nReview of full workshop\nInteractive Question and Answer (Q&A) session\n\nAdjourn
