RAPID: Adaptive management of geotechnical construction in urban areas

Project: Research project

Project Details

Description

Recent research has resulted in advances in techniques to predict, monitor, and control ground
movements during excavation. The purposes of this proposal is to employ adaptive management
techniques for geotechnical construction to provide real time updates of performance predictions and
to develop design procedures that are applicable to urban excavations that use existing structures as
lateral support. This proposed research builds upon the results of several of NSF-supported projects in
which the optimization techniques were developed, automated monitoring technologies were
employed, full-scale field performance was quantified in detail, sophisticated constitutive models were
employed and parameter identification techniques were quantified at deep excavation sites. The
adaptive management technique has not yet been applied to excavations in real time, primarily for a
lack of reliable automated means to measure lateral movements with depth adjacent to an excavation,
and for ambiguity of the causes of ground movements with respect to construction activities and
structural responses.
