Their talk concerns the collapse of the 26th Street retaining wall in Baltimore that was captured on cell-phone video. This dramatic event was seen on YouTube and all of the TV News channels. Every geologist should know be familiar with this very public issue and the actions taken to fix our crumbling infrastructure. The meeting is at Brewer’s Alley in Frederick.

SECTION MEETING
Baltimore MD – Washington DC – Harrisburg PA

TOPIC: Emergency Retaining Wall Replacement, 26th Street, Baltimore, MD

Abstract:
After significant rainfall in Baltimore City on April 30, 2014, the
retaining wall between 26th Street and the CSX tracks collapsed. 26th Street was
closed between Charles Street and St. Paul Street while the roadway was
stabilized, utilities were replaced, and construction began for a new
retaining wall. The project consisted of constructing a temporary soldier pile
and lagging wall with 3 rows of anchors. Between the temporary support of
excavation and the railroad tracks, a new gravity retaining wall will be
constructed. The presentation includes discussion of the technical aspects of
the emergency response, the geotechnical design and the construction of the
replacement wall.
