The author describes the various project constraints, installation challenges, and full-scale testing of the new foundations, which incorporated six different pile types. DEEP FOUNDATIONS • JAN/FEB 2019 • 5 Drilled displacement systems that densify coarse-grained soils by mechanically displacing the soils laterally can provide an efficient alternative for the mitigation of liquefaction- induced settlement and structure movement due to lateral spread. The author provides background on drilled displacement elements/piles, their use as ground improvement systems, and a mini-case history. 75 Column Supported Embankments at I-295/ I-76/Rte 42 Direct Connection Project Nina F. Carney, P.E., Sarah K. Ramp, P.E., and Dylan P. Davis Rigid inclusions were installed to mitigate potential settlement and improve the external stability and bearing characteristics of the mechanically stabilized earth walls and embankments constructed to raise the grades for the new interchange. The authors present a synopsis of the design, stability analyses and estimation of settlement along with the various challenges faced on the project sites. W.
