Benjamin Zand will present “Effect of Construction and Blast Vibration on Buried Pipelines,” as a live webinar on Thursday, May 14, 2021.
This training has the minimum required to hold the class. Further information to be provided upon registration.

Introduction

The Effects of Construction and Blast Vibration on Buried pipelines is a one-day course which 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, jack hammer) and blast operation near a buried pipeline will be discussed and engineering methods to calculate vibration induces stresses will be reviewed. We will also review acceptance criteria for vibration induced stresses in a buried pipeline.

Pre-Requisites

Familiarity with stress, strain, deformation and their relationships.

Who Should Attend

– Pipeline engineers
– Consulting engineers
– Any technical individual with pipeline integrity responsibilities

Course Outline

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)
8- Closing

*Hourly breaks and 50-minute lunch included.
