Developing Scour-Depth Estimation Using the In Situ and Portable Scour Testing Devices (ISTD and PSTD) for Illinois Cohesive Soils
More than 60% of bridge failures in the United States are due to scouring and only 2% of the failures are caused by earthquakes. Many studies have been done on bridge scour predictions during the past decades. Most of the studies prior to 1999 were performed on non-cohesive materials. The most common prediction methods were proposed by HEC−18 and were later modified by Arneson et al. in 2012 (HEC 18 2012 version) to address scour calculations in cohesive material. FHWA in recent years developed the Insitu Scour Testing Device (ISTD) and Portable Scour Testing Device (PSTD) to extract better load versus erosion characteristics of the riverbed material. The objective of this research is to establish testing and hydraulic-analysis procedures with ISTD/PSTD data and to improve reliability of the estimated scour depths in cohesive soils to design bridges more cost-effectively. To meet this objective, the researchers will complete the following step: conduct a literature review, perform field testing and collect samples, develop a procedure, and publish a final report.
