Prediction of End Of Construction Undrained Deformations of Atchafalaya Levee Foundation Clays.

Abstract

Levee construction in south-central Louisiana has proven to be very time consuming and expensive because of excessive movements within the soft, highly plastic, thick deposits of the foundation soils. Field measurements from three well instrumented test sections constructed along the East Atchafalaya Basin Protection Levee (EABPL) have led to the belief that undrained shear strains and long term lateral creep deformations are major factors contributing to the very large settlements of the levees. This report presents the results of finite element predictions of the end of construction lateral deformations on the floodwayside of the EABPL Test Sections II and III. The M.I.T. computer program was used for the analysis and realistically modeled the actual sequence of construction.
