Benjamin Zand will present “Effects of Construction and Blast Vibration on Buried Pipelines” as a Webinar on January 26, 2022.
This class has met the minimum to be held and is continuing to accept registrations.
The Effects of Construction and Blast Vibration on Buried pipelines is a one-day course that covers the effects of vibration from blasting operation and construction activities on buried pipelines. In this course, you will learn:
1. Generals of ground vibration
2. Acceptable vibration levels for a buried pipeline
3. Integrity issues due to vibration and blast operation
Vibration from construction equipment (e.g. vibratory compactor, pile driving, jackhammer) and blast operation near a buried pipeline will be discussed, and engineering methods to calculate vibration induced stresses will be reviewed. We will also review acceptance criteria for vibration induced stresses in a buried pipeline.
Familiarity with stress, strain, deformation and their relationships.
Who Should Attend
– Pipeline engineers
– Consulting engineers
– Any technical individual with pipeline integrity responsibilities
1. Review of wave propagation in the ground – This section covers various types of waves including p-wave and shear wave and their propagation velocity in an elastic medium
2. General characteristics of construction vibration
3. Wave attenuation and peak particle velocity – This section covers peak particle velocity and how it attenuates with distance from a vibration source
4. Transportation and Construction Vibration Guidance Manual, Caltrans – this section covers a practical approach for the prediction of peak particle velocity from various types of construction equipment and activities based on Caltrans guidance manual with some examples
5. Generals of Blast Operation – This section covers general principles of blast operation and terminology used by blast contractors such as explosive charge mass, scaled distance, delay per charge, and blast design
6. Esparza’s work – covers the experimental and analytical work by Peter Esparza on the effect of blasting on buried pipelines. The analytical and experimental background of Esparza’s equations are described, the application and unit system of the equations are discussed with some examples
7. Other issues (block movement, fatigue crack growth, monitoring)
*Hourly breaks and 50-minute lunch included.

Dr Zand has 20 years of experience in geotechnical engineering, geohazard assessment, stress analysis, pipeline integrity assessment, mechanics of composite material, and mathematical modeling. His experience includes stress and vibration analysis and monitoring for oil and gas transport pipelines and facility piping. Dr Zand has assisted pipeline operators with geohazard problems such as longwall mining subsidence, ground movement, sinkhole, earthquake and fault crossing. Dr Zand has developed mitigation and monitoring programs for pipelines subjected to various geohazard conditions. He has assessed numerous pipelines subjected to vibration and cyclic loading from blast and construction. He previously worked with Kiefner & Associates, Inc. (2012 to 2019) and has recently joined RSI Pipeline Solutions, LLC. He has served as an instructor for Rock Mechanics course at the Ohio State University.
