Abstract
This project describes and validates the
design of a slope stabilization technique for the
Bechara Middle Section (BMS) channel located in
the Bechara Industrial Area, San Juan, Puerto
Rico. The BMS project consisted of approximately
720-foot earth open-channel and is a
subcomponent of the Rio Puerto Nuevo Flood
Control Project constructed by the US Army Corps
of Engineers. Pre-construction soil conditions in
the site consisted of soft clays and organic material
that precluded the excavation of the proposed
channel geometry. The soil slope stabilization
design option for the BMS was two continuous soil
treated zones, A and B, by means of improving the
existing soft soil conditions with the technology of
Deep Soil Mixing. The slope stability of the channel
was analyzed by modeling the improved soil in
GeoStudio-Slope/W and was found to be in
compliance with the required safety design factors.
