• Abstract:
  The construction of embankments and other infrastructure elements over saturated, compressible, cohesive soft soils in Louisiana presents significant geotechnical design challenges due to anticipated large magnitudes of consolidation settlement and slow rates of consolidation. Inaccurate estimation of these deformations can lead to significant differential settlements, loss of serviceability, structural damage, unsafe drivability, and increased maintenance costs. Therefore, accurate assessment of infrastructure settlement behavior and reliable estimation of the different consolidation parameters, such as constrained modulus (M), compression and recompression indices (Cc & Cr), horizontal and vertical coefficients of consolidation (Ch, Cv), and over consolidation ratio (OCR), are essential for the design and long-term performance evaluation of different infrastructure elements in such conditions.
