Abstract
In this project, Illinois-specific design procedures were developed for drilled shafts founded in weak shale. In addition, recommendations for field and laboratory testing to characterize the in situ condition of weak shales in Illinois were developed and presented herein. For this project, weak shale is defined as an intermediate geologic material (IGM) with an unconfined compressive strength of 10 to 100 ksf. These investigation and design improvements are anticipated to lead to safer design and substantial deep-foundation cost savings for IDOT.
