treatment process using a wave tank to identify optimum
ranges of cementation for treatment of coastal deposits.
4. conclUsions
micp can be used to reinforce sandy coastal deposits to
improve the resiliency of vital lifelines during large storm
events. soil columns of clean fine sand were treated with
micp, and resulted in lightly cemented sand. the lightly
cemented sand had an increase in strength, as demonstrated
with the unconfined compression tests, and increase in friction
angle. the free-draining treatment process was designed to be
similar to likely treatment processes of unsaturated surficial
sands in situ. this treatment process provided uniform levels
of cementation throughout the height of the soil column. the
light levels of cementation achieved in the soil columns
provide an increase in shear strength while still allowing for
birds, burrowing animals, and dune grass to interact with the
coastal deposits. future work involves investigating the
optimal range of micp cementation to provide enough
strength to resist the loads from large storm events while
continuing to support the coastal ecology.
