Retrogressive Failures in Sand Deposits of the Mississippi River. Report 1. Field Investigations, Laboratory Studies and Analysis of the Hypothesized Failure Mechanism
This report is the first of a series documenting recent studies directed at determining the causes of, understanding the mechanism of, and developing defenses against retrogressive failures (flow slides) in sand deposits of the Mississippi River which threaten the safety of mainline flood protection levees below Baton Rouge, LA. A review of the literature tracing the progress of associated antecedent studies since their inception in the late 1940's is presented. Recent field and laboratory investigations relative to the Montz and Bonnet Carre Point, LA, failure sites are described and analyzed to infer the in situ character of the sand deposits. Results obtained form several in situ investigation techniques including fixed-piston undisturbed sampling, standard penetration testing, cone penetration testing, piezocone penetration testing, and Delft resistivity cone penetration testing are presented and compared. Geologic and historic hydrographic studies of the two sites are also included. Keywords: In situ tests, Retrogressive failure, Riverbank stability, Sand flow mechanism. (jes)
