Session 01: Case Histories of Unexpected Behavior and Failure of Shallow, Deep and Other Foundations
Location

Abstract
Near-surface groundwater levels and high flood levels associated with flooding events impose significant hydrostatic forces on subterranean parking structures in Florida. Unique geologic conditions and the associated high hydraulic conductivities of the subsurface materials have precluded the use of conventional underdrain systems to provide hydrostatic relief. The case history presented here discusses the evaluation and repair of a subterranean parking garage of an existing office building that exhibited signs of distress including severe cracking of the ground floor slab, excessive quantities of water continuously seeping through these cracks and ponding water. Although various rehabilitation alternatives were evaluated, removal, replacement and re-design of the existing slab were chosen in order to provide additional tie-down restraint and implement a relatively maintenance-free, long-term solution. This paper briefly describes geologic conditions, the results of site-specific subsurface investigations, historical groundwater information, and various regional and local subterranean design alternatives. The design and construction aspects of the implemented anchored hydrostatic uplift slab system are presented, including: anchor installation, performance and proof testing, construction dewatering, waterproofing issues, and chemical grouting of joints.

Evaluation and Repair of a Subterranean Parking Garage to Resist Hurricane Flood Levels
