Trabuco Creek: Drilled Shaft Defect Identification and Mitigation
Authors: Sarah Skeen and Brian A. LiebichAuthor Affiliations
Publication: Geotechnical Engineering for Transportation Projects
Abstract
This paper will illustrate the use of non-destructive testing (NDT) as a means to verify the quality of the construction of drilled shafts. A review of the recent advances and direction of the Federal Highway Administration (FHWA) on this issue will be provided. The NDT methods emphasized will be Gamma-Gamma Logging and Crosshole Sonic Logging and the use of the two in concert will be examined. The mitigation process for defects identified within shafts will also be addressed. The Trabuco Creek Bridge Project will also be utilized as a case study to illustrate the concepts forwarded in this paper.
