Abstract:

Significant portions of overall design and construction costs for Florida bridges are typically attributed to deep foundation components. Such costs arise because soils are highly variable materials; measured soil properties typically exhibit spatial variability across a given site, both with respect to depth and horizontal position. In addition, empirical methods by which measured and lab-determined soil properties are correlated to design-relevant soil resistance quantities introduce a separate form of uncertainty into the design process. Directly accounting for these two distinct sources of uncertainty (spatial variability, method error) in bridge foundation design can bring about improved (1) soil or rock layering as well as zones or regions to reduce coefficients of variation and (2) increased reliability-based foundation configurations for given boring and strength data. As part of previous research funded by Florida Department of Transportation, geostatistical techniques and method-error characterizations were coded into a prototype software tool. The current project was undertaken to transition the software from a research tool into a design tool, referred to as GeoStat. Detailed in this report are efforts and outcomes associated with (1) establishing an input file format and data read/write operations; (2) automation of calls to pre-existing pile/shaft axial capacity calculation software; (3) quality assurance testing; (4) development of an installation package and licensing; (5) development of a software user manual; (6) development of a software technical manual; and, (7) deployment of the software. Accordingly, the GeoStat software is ready to be officially deployed so that it can be made use of by practicing engineers.
