Full Presentation

This presentation will briefly review several waste fill stability failures from the time-frame of the early 1980s to mid 1990s and the lessons learned during that period. Notwithstanding the lessons learned, waste fill failures continue to occur. Several from the current decade are reviewed and it is concluded that 20 to 30 years after the earlier time-frame, facility owners and the geotechnical practitioners designing those facilities are re-learning the earlier lessons, while at the same time there are new lessons to learn related to evolving waste streams and operating practices at many U.S. facilities.

Learning Objectives:

  • Recognize that the potential modes of geotechnical instability of waste fills.
  • Understand the factors that led to several notable historical waste fill failures and the lessons learned.
  • Recognize that new factors are contributing to waste fill failures in the current decade.

Full Presentation

Developments in the design of deep supported excavations have been driven by field observations collected during construction of such systems. The lecture illustrates this by presenting a number of aspects of design related to both limit state and serviceability. Field performance data are discussed relating to lateral loading diagrams for internally braced excavations, stiffness based design based on allowable deformations and current capabilities with respect to prediction of ground deformations both during the design stage and as construction proceeds. This “adaptive management” approach is an extension of the classical observational approach long advocated by Prof. Peck.

Learning Objectives:

  • Understand how field observations formed the basis of design of excavation support
  • Understand the different approaches for limit and serviceability based design of excavation support
  • Understand the observational approach entails more than observations

In May 2018, a team of geoprofessionals went on an ASCE G-I-sponsored trip to China, to observe ground improvement technologies commonly used in that country. Team members on the so-called ASCE China Scan Tour consisted of practitioners and academicians from the United States and Canada. The team visited six job sites and observed the application of a wide range of ground improvement technologies, including diaphragm walls, recoverable/reusable anchors, soil mixing, different types of vacuum consolidation, and electro-osmosis. The trip culminated with the 2nd China-U.S. Workshop on Ground Improvement that was jointly organized with the Chinese Institution of Sol Mechanics & Geotechnical Engineering and held on May 27 in connection with the GeoShanghai International Conference. The team has completed a report that will be made available by the Geo-Institute soon. This presentation will provide a summary of the China scan tour on ground improvement technologies.

Learning Objectives:

  • Common practice of ground improvement technologies used in China
  • New advances and innovations of ground improvement technologies

This paper observes how acquisition and storing drilling data has gone long ways from collecting it with pen and paper and archiving it into carton boxes back in the day, to collecting it or transforming it into electronic form and storing it into the cloud these days. We look why this happened, what enabled it, and how this shaped a contemporary subsurface data flow from raw data to data represented geospatially, to interpreted data turned into information, to interpolated data turned into 3D models that are used in collaborative environments and Building Information Modeling (BIM).

Learning Objectives:

  • How to manage down-to-earth data up in the cloud
  • How to geotechnical engineers can share their information in real-time, in a collaborative environment with other engineering disciplines
  • Understanding Geotechnical Building Information Modeling (BIM)

Strahimir (Strah) Antoljak has a master’s degree in structural engineering from University of Zagreb (Croatia) and in geotechnical engineering Rutgers, The State University of New Jersey. He serves as a National Manager at Terracon, and a go-to person and technology evangelist for enterprise-level subsurface data management, GIS and CAD interoperability, geotechnical BIM, subsurface modeling, and geotechnical lab reporting management. Prior to Terracon Strah was a geotechnical software product management at a major software company conveying geotechnical engineering needs into streamlined processes and more effective and cost-effective workflows using software and technology in general. Strah was a presenter at many engineering software technology conferences organized by Autodesk and Bentley.

Recent advances in sensor systems offer intriguing possibilities to radically alter methods of condition assessment and monitoring of geotechnical infrastructure. In this talk, it is hypothesized that the future of geotechnical infrastructure relies on smarter information; the rich information obtained from sensors within infrastructure will act as a catalyst for new design, construction, operation and maintenance processes. Some examples of emerging sensor technologies for infrastructure sensing are given. They include distributed fiber-optics sensors, computer vision, wireless sensor networks, low-power micro-electromechanical systems, energy harvesting and citizens as sensors.

Learning Objectives:

  • Learning new emerging sensor technologies
  • Seeing how new technologies are used in geotechnical engineering practice
  • Examining the value of sensing in geotechnical engineering

Full Presentation

In the early morning hours of 12 February 2014, the National Corvette Museum (NCM) and the Bowling Green, Kentucky community were awakened to the realization that Mother Nature is still in control. Who would have ever expected that a sinkhole large enough to swallow 8 Corvettes would open anywhere in the world, much less inside the iconic Frustum at the National Corvette Museum?
This presentation will highlight key points from that early morning to the conclusion of the first phase of stabilization and remediation of the project site.

Learning Objectives:

  • The importance of a thorough initial geotechnical investigation of a proposed site.
  • The possible catastrophic failure that can occur even when a ‘thorough’ geotechnical investigation is conducted.
  • Methods to address the remediation of a catastrophic sinkhole collapse.

Dennis D. Smith, PE, PLS, F.ASCE, F.NSPS is President and CEO of DDS ENGINEERING, PLLC in Bowling Green, KY. DDS is a Surveying, Civil and Geotechnical Engineering Firm and has been directly involved with the National Corvette Museum (NCM) since its initial construction in 1994. He and his wife were founding members of the NCM and DDS has been instrumental with expansions to the NCM as well as being the prime consultant for the NCM’s Motorsports Park. Besides the fire department, Dennis was one of the first to respond to the NCM that fateful day.

K-7 Mine Remediation

The proposed KDOT widening of K-7 extended above existing mine voids from the abandoned coal seems which varied from 18'-50' below existing ground surface. Portions of the alignment had experienced sinkhole activities previously and some pressure grouting had been performed previously with some success. Specialty grouting equipment and project team collaboration allowed for the project to be completed on time and on budget.

Learning Objectives:

  • Geotechnical investigations of abandoned mine workings can often identify collapsed mine rubble or sediments as open voids. Down hole camera inspection of apparent voids during geotechnical program can greatly benefit the geotech data for use in planning the grouting protocol.
  • Development of a clear grouting protocol with acceptance criteria is critical to project effectiveness and efficiency. The "lets wait and see how the first hole goes approach" to acceptance criteria leads to confusion and inefficiency in the field. Development of a joint grouting protocol with owners engineers and contractors grouting staff can greatly benefit the project.
  • Video monitoring of grouting is a great visual aid when in large mine openings but should be used a as supplemental grout verification after well established grouting protocol.

Joe is the regional Vice President for the Rocky Mountain region of Hayward Baker. Joe started in the Geotechnical field at the age of 19 and now has 35 years of experience in Geotechnical construction, Ground Improvement, risk mitigation, and structural support. Joe has authored numerous technical papers on Compaction and Low Mobility grouting and has been involved with over 3000 grouting and ground improvement projects worldwide.
