Non-Destructive Testing for Drilled Shafts
This engineering online CPD video presentation will deliver a focused, practical overview of non-destructive testing in drilled shafts, designed to help engineers detect and address potential defects.
As critical foundation elements in large infrastructure projects, drilled shafts require precise construction and thorough monitoring to prevent costly issues. This presentation includes a brief history and evolution of drilled shafts, followed by a review of key construction methods and the root causes of common defects.
This video presentation will examine typical construction challenges such as misalignment, poor concrete placement, and other flaws affecting structural integrity. Defects will be categorized, and advanced non-destructive testing techniques like Crosshole Sonic Logging (CSL), Crosshole Tomography (CT), and Sonic Echo (SE) will be introduced. These methods allow for the accurate diagnosis of the drilled shaft without damaging the structure. It also outlines repair techniques and risk mitigation strategies aimed at improving quality control and long-term shaft performance.
This 2 CPD online video presentation is intended for civil, geotechnical, structural, and construction engineers as well as professionals seeking to enhance their understanding of drilled shaft construction and quality assurance through non-destructive testing.
This continuing education video presentation is intended to provide you with the following specific knowledge and skills:
- Exploring primary construction methods for drilled shafts, including dry, wet, and casing techniques.
- Familiarizing yourself with frequent construction challenges and their potential impact on shaft performance.
- Understanding typical defects encountered in drilled shafts.
- Introducing non-destructive testing (NDT) techniques used for evaluating shaft integrity, including Crosshole Sonic Logging (CSL), Crosshole Tomography (CT), Perimeter Sonic Logging, Sonic Hole Sonic Logging, Gamma-Gamma Logging (GGL), Sonic Echo (SE), and Thermal Integrity Profiling (TIP).
- Reviewing remedial methods used to address structural deficiencies in drilled shafts.
- Examining risk mitigation practices, including fundamental repair strategies and various grouting solutions.
