Abstract

The article focuses on the challenges and solutions related to gas extraction and in situ oxidation for tunnel boring machine (TBM) tunneling of the Purple Line Extension, Section 1, in Los Angeles. Topics include the historical background of the project, the impact of methane seepage on previous construction plans, and the comprehensive investigations and mitigations implemented to safely tunnel through gassy ground, particularly the Crescent Heights Gas Zone.
